Joseph Gordon-Levitt in Looper (2012)
Makeup artist Kazuhiro Tsuji use contact lenses and subtle prosthetics to turn Gordon-Levitt into a younger version of Bruce Willis, a process that took about three hours a day. "I thought he just looked strange and different from how I imagined him looking. I was more just weirded out than anything else," Looper co-star Emily Blunt told EW. "I convinced myself, oh my God, I?m not talking to Joe, what am I doing, I?m obviously talking to his stunt man."

Sean Penn in Gangster Squad (2013)
Thanks to facial prosthetics, waxy makeup and pinstriped period costumes, Penn bears an uncanny resemblance to Brooklyn-born mafia boss Mickey Cohen in the 1940?s crime drama, which hits theaters next summer.

Will Smith in Ali (2001)
It took more than a 35-pound weight gain, a flat top hairstyle and the special mold the actor wore between takes to keep his ears from sticking out on camera to get Smith ready for the role that would score him an Oscar nomination. "It's everything from Will taking Islamic studies to becoming a boxer. Not learning how to box, not figuring out how to fake it, but becoming a boxer. From that to working on the regional origins of Ali's speech patterns to the point that Will would be dreaming in Ali inflections... it's not mimicry," director Michael Mann told EW of the actor's yearlong process of self transformation.

Chris Evans in Captain America: The First Avenger (2011)
Before he could become Captain America, Evans first had to morph into 98-pound weakling Steve Rogers, a visual effects process that involved digitally shrinking parts of the actor's body by up to 30%. "Initially... they thought, 'Well, maybe we can get another skinny actor and put Chris' head on it,' and I really, really was against that. I said to Joe [Johnston, director], 'Look, I know we want this to look good and this effect to not be distracting from the film, but it has to be my performance. I don't want to share this. Your body is a huge piece of the acting puzzle, and I don't want to have somebody else's body tell the story that I'm trying to tell,'" Evans told USA Weekend.

Ron Perlman in Hellboy 11: The Golden Army (2008)
Perlman personally selected visual effects makeup artist Jake Garber to create his Hellboy character. For four hours each day, Garber and his team readied the actor for his scenes by applying foam pieces to his back, chest and neck, a full-face prosthetic, a samurai wig, side burns and a goatee, dentures, and full-eye contact lenses. An elaborate painting process included the blending of several shades in order to get Perlman's Hellboy red coloring just right.

Al Pacino in Dick Tracy (1990)
Though all of the other villains' looks stayed true to the Chester Gould comic strip that inspired the film, Pacino himself re-imagined the Big Boy Caprice character. After helping the actor make his vision a reality, John Caglione Jr. became Pacino's go-to makeup man.

Ralph Fiennes in Harry Potter and the Deathly Hallows (2010)
To create Voldemort's freaky face, a gelatin application was used to cover the actor's eyebrows and forehead, creating the appearance of ominous, more deeply set eyes. Tracking dots applied to the actor's face during filming helped visual effects artists digitally replace his nose with a snakelike snout and give his skin a milky sheen during the editing process.
