Bryan Cranston learned how to ‘cook’ for Breaking Bad

In order to make sure the show was as authentic as possible, the producers of Breaking Bad hired Drug Enforcement Agency officers as consultants, and they put their knowledge of chemistry to a rather unexpected use. DEA agents taught Cranston the exact process for manufacturing Walter White’s illicit product, which the actor described as “very interesting, intricate, and dangerous.” Whilst the DEA are literally the last people you would expect to be teaching anyone how to make drugs, they probably felt fairly certain that Cranston wasn’t about to abandon his acting career and break bad.

Jennifer Lawrence learned how to skin squirrels for Winter’s Bone

Whether or not this is a transferrable skill is debatable, but Jennifer Lawrence mastered the technique of skinning squirrels for 2010’s Winter’s Bone. If you thought the squirrel skinning looked uncomfortably real, that’s because it is. Exactly how many squirrels Lawrence went through whilst practising is unknown, but, considering the level of expertise with which she carried out the gruesome task, it’s safe to say the number is greater than zero.

Olivia Munn mastered sword fighting for X-Men: Apocalypse

It’s not often that you get to learn sword fighting as part of your professional life, but this is exactly the opportunity that Olivia Munn was presented with when she was cast as Psylocke in X-Men: Apocalypse. Munn spent five months before production intensely training with a katana – more commonly known as a samurai sword – and she got adept enough to perform 95% of her own stunts in the movie. The actress enjoyed sword fighting so much that she carried on training after filming ended.

Kate Winslet learned how to free dive for Avatar 2

Freediving – the art of swimming to incredible depths whilst holding one’s breath – is a notoriously dangerous pursuit, and multiple professional freedivers have perished during competitions. However, this didn’t deter Kate Winslet from immersing herself in the sport prior to filming Avatar 2, which saw the actress cast as a ‘water Avatar’. Winslet, who later described her training as “crazy, crazy stuff,” became an extremely accomplished freediver, clocking in a maximum breath hold of seven minutes and 14 seconds.

Uma Thurman became an expert martial artist and learned Japanese for Kill Bill

The Bride, Uma Thurman’s character from the Kill Bill films, is undoubtedly one of Quentin Tarantino’s most iconic creations. Preparation for the role required Thurman to learn three different styles of Kung-Fu, two styles of sword fighting, hand-to-hand combat, knife throwing, knife fighting, and – last but not least – Japanese. Learning any one of these skills would have been impressive, but the actress nailed all of them. However, one area she probably could have worked on was her driving. Whilst filming a chase sequence for Kill Bill: Volume 2, Thurman lost control of the vehicle and crashed, injuring herself and causing a lasting rift between her and Tarantino.

Margot Robbie learned how to figure skate for I, Tonya

Figure skating is a skill that’s notoriously difficult to learn, requiring an impressive combination of athleticism, coordination, and sheer fearlessness. When preparing for 2017’s I, Tonya, Margot Robbie spent five hours a day on the ice for a period of five months under the expert tutelage of Sarah Kawahara. As well as having to quickly reach a high level of proficiency – no easy feat in itself – Robbie had to be comfortable enough on the ice to be able to act whilst skating. Her dedication paid off, and Robbie was nominated for the Academy Award for Best Actress for her nuanced portrayal of Tonya Harding.

Natalie Portman learned ballet for Black Swan

Widely regarded as one of the most difficult forms of dance to master, ballet is notorious for the physical toll it exacts on its practitioners’ bodies. However, Natalie Portman didn’t let this discourage her when it came to preparing for her lead role in 2010’s Black Swan. Despite being offered a dance double, the actress devoted months of her life to learning ballet, spending six hours a day engaged in gruelling training. Whilst the actress later revealed that the process made her feel like was “literally going to die,” her results paid and she performed most of the dance sequences in the film.

Mahershala Ali learned piano for Green Book

When he was cast as famous jazz musician Don Shirley in 2018’s Green Book, Mahershala Ali devoted himself to mastering the piano. Ali recruited the help of Kris Bowers, the film’s composer, to get him up to scratch on the keys. Bowers later recounted the extreme discipline that Ali brought to the challenge; in their first lesson, the composer had planned to teach Ali some basic scales over the course of an hour. However, the actor was still at the piano three hours later, playing the C major scale over and over again.

Robert Downey Jr learned to play the violin for Chaplin

Silent film star Charlie Chaplin was known to take his beloved violin with him everywhere he went and was a highly talented musician. When Robert Downey Jr was cast as the comedian in 1992’s Chaplin, he devoted himself to mastering all of Chaplin’s mannerisms and skills – including the violin. On its own, this would have been no mean feat, as the violin is considered one of the hardest instruments to learn, but what really elevated Downey’s dedication was the fact that – to keep things authentic – the right-handed actor learned to play left-handed.

Adrien Brody learned to play the piano for The Pianist

Compared to some of the extreme lengths that Adrien Brody went to for his role in The Pianist – such as losing a dangerous amount of weight and selling most of his worldly possessions – mastering the piano probably felt like a walk in the park. However, this doesn’t detract from the actor’s musical efforts, as learning any instrument takes extreme focus and dedication – especially if you’re malnourished. Brody’s portrayal of Jewish pianist Władysław Szpilman was roundly hailed as a masterpiece.

Joaquin Phoenix learned the guitar for Walk the Line

Joaquin Phoenix is known to take a method approach to preparing for his roles, so it’s not surprising that he took the opportunity to learn the guitar when he was cast as Johnny Cash in 2005’s Walk the Line.

Reese Witherspoon, who also stars in the movie, displayed the same level of dedication and learned the autoharp for her role.

Daniel Day Lewis learned how to track and hunt animals for The Last of the Mohicans

Daniel Day Lewis is renowned for his extreme dedication to his roles, often spending months in character before filming begins. When the actor was cast as Hawkeye in 1992’s The Last of the Mohicans, he decided to go off grid and live as a survivalist. In the course of his preparation, Day Lewis became adept and tracking, stalking, and hunting animals, as well as skinning and gutting their carcasses and cooking them in the wild.

Channing Tatum learned to tap dance for Hail, Caesar!

Channing Tatum became a household name with Step Up, and he proved that no style of dance is beyond his reach when he mastered tap dancing for Hail, Caesar!. The tap dancing scene only takes up a few minutes of the film, but Tatum spent three months working on making sure his moves were on point. It’s hard to imagine much phasing Tatum after he starred in Magic Mike, but the actor stated in an interview, “when I’m nervous about something, I drill it to a point that is probably unhealthy.”

Tom Cruise learned how to fly helicopters for Mission Impossible: Fallout

Tom Cruise is known to have a fondness for doing his own stunts, and he has used the Mission Impossible franchise to put himself in a variety of dangerous situations. Whilst learning to fly a helicopter isn’t quite as daring as hanging off the side of a plane taking off, it’s still quite the challenge and comes with its fair share of dangers. Whilst preparing for the role, Cruise spent a staggering 2,000 hours – or 83 solid days – learning how to expertly fly choppers for an adrenaline-filled chase sequence.

Timothée Chalamet learned Italian and spent hours practicing the piano and guitar for Call me By Your Name

One of the brightest emerging talents in Hollywood, Timothée Chalamet earned critical acclaim for his role in 2017’s Call me By Your Name. The actor is fluent in both English and French, but he had a harder time getting to grips with Italian and flew out to Italy a month and a half before filming began to immerse himself in the language. Chalamet had played instruments as a kid, but he also studied guitar and piano with Italian composer Roberto Solci to brush up his skills for the film.

Danai Gurira became an expert sword fighter for The Walking Dead

Michonne Grimes is undoubtedly one of the coolest characters in AMC’s zombie series The Walking Dead. Ruthless and fearless in equal measure, Michonne uses her katana to effortlessly carve through hordes of zombies. To prepare for the role, Gurira spent countless hours training in sword fighting, and got so good that she started contributing to the show’s choreography. The actress compared sword training to “swinging a five foot dumbbell”, and continues to incorporate it into her fitness routine.

Chadwick Boseman learned the trumpet for Ma Rainey’s Black Bottom

Whilst preparing for Ma Rainey’s Black Bottom, which would tragically prove to be his final film, Chadwick Boseman learned how to play the trumpet. Despite only having three valves (also known as buttons), the trumpet is a notoriously difficult instrument to master, and Boseman had never played the instrument before. However, the actor devoted himself to learning it, and Glynn Turman, Boseman’s co-star, recalled hearing him practising in his hotel room whenever they weren’t filming.

Ryan Gosling learned carpentry for The Notebook

As soon as he heard that he’d landed the role of Noah Calhoun in 2004’s The Notebook, Ryan Gosling got to work learning how to make furniture. The actor apprenticed with a cabinet maker and spent months honing his carpentry skills. Impressively, the actor got so good that many of his creations ended up being used as furniture in the film. It wasn’t the first time that the actor had gone method.

Joseph Gordon-Levitt learned how to tightrope walk for The Walk

2015’s The Walk saw Joseph Gordon-Levitt cast as Philippe Petit, a daredevil who tightrope walked between the Twin Towers in 1974. To make the film’s tightrope sequences look authentic, Gordon-Levitt learned the skill for real, and he had the perfect teacher: Philippe Petit himself. The high-wire artist coached Gordon-Levitt extensively, and by the time he was done with him the actor could comfortably walk across a wire unaided – although he kept things close to the ground, unlike Petit, who walked over a 1,312 foot drop during his 1974 stunt.

Russell Crowe learned how to play the violin and sail a ship for Master and Commander: The Far Side of the World

When Russell Crowe was cast as Captain Jack Aubrey in the gritty naval drama Master and Commander: The Far Side of the World, the actor spent months learning the skills of a 19th century sailor.

Jesse Eisenberg learned magic tricks for Now You See Me

Considering the fact that Jesse Eisenberg’s character in Now You See Me is supposed to be one of the best magicians in the world, it’s not surprising that the actor felt compelled to brush up his magic skills.

In an interview, Eisenberg stated, “if you learn some of the basic principles you can apply those principles to many different tricks or illusions.”

Rooney Mara learned how to hack computers for The Girl With the Dragon Tattoo

The way hacking is depicted in films is the subject of much mockery, with characters bashing away at their keyboards with an intense look on their face before uttering the immortal, “I’m in.” Rooney Mara clearly wanted to make sure her depiction of hacking in The Girl With the Dragon Tattoo was more realistic, and the actress took extensive computer science lessons and learned how to hack for real. Her all-around dedication to the part was rewarded with critical praise.

Jon Favreau learned how to cook for Chef

2014’s Chef was an unexpected gem, largely thanks to Jon Favreau’s endearing performance as a chef who turns his back on haute-cuisine to operate a food truck with his son. Despite the fact that for most of the film Favreau’s character is making Cuban sandwiches, the actor still went to culinary school to prepare for the role. Whilst this might have been overkill, it all worked out well in the end, leading to the creation of Favreau’s Netflix series The Chef Show.

Leonardo di Caprio and Tom Hardy learned an indigenous dialect for The Revenant

2015’s The Revenant features many scenes involving Native American tribes, particularly the Arikara. To make the film as authentic as possible, both Leonardo di Caprio and Tom Hardy worked with an indigenous cultural consultant to master the tribe’s complex dialect.

The actress didn’t have much experience with the game before she was cast, but she said that honing her chess skills made her “feel closer” to her character.

Michelle Pfeiffer learned how to wield a whip for Batman Returns
