10 Actors Who CHEATED Incredible Body Transformations For Movies

5. Robert Downey Jr - Avengers: Endgame

Given that Robert Downey Jr was reportedly paid upwards of $75m to appear in Avengers: Endgame, you'd think he'd have no issue going full method for his final appearance as Tony Stark. Then again, he's also Robert Downey Jr, which is precisely why he was paid that much money and that sort of profile (and value) means you're beyond that sort of thing.

RDJ has always been an athletic guy as Tony Stark (helped in no small part by the actor's commitment to the art of Wing Chun) but Endgame asked him to do something most superhero movies don't require: it asked him to cut his weight dramatically.

When Tony is stranded in space, he loses a huge amount of weight over 22 days without a real food supply and returns to Earth emaciated, frail and on the verge of death. But rather than following in Christian Bale's footsteps and methoding his way to extreme weight loss, Downey Jr's transformation was done digitally.
