Five Actors Who Vanished Into Someone Else's Voice

Somewhere between imitation and full transformation is where the best biopic performances live, and a new Stallone film trailer is the starting point for tracking down exactly where that line sits. The actor behind it built a voice from nothing that fooled listeners into thinking it was the real Sylvester Stallone. That single clip opens into a run through five performances that hit that same mark: Jamie Foxx channeling Ray Charles by ear alone, Val Kilmer becoming Jim Morrison, Joaquin Phoenix's Johnny Cash, and Austin Butler's Elvis. Each one gets tested against the real recordings to see how the transformation was actually built. The pattern that emerges says something bigger about what makes a performance stick with an audience long after the credits roll, and why some actors playing real people never quite get there.
