Who could this elderly gentleman be? Of course, it's Brad Pitt! He had to undergo a number of physical changes to look the way he did in The Curious Case Of Benjamin Button! Major props to the makeup artist! Like many of his fellow actors who underwent a drastic transformation, the 57-year-old was nominated for an Oscar, too!

Beer belly and flip-flops anyone? We had to take a second glance to recognize Hollywood superstar Christian Bale! The usually handsome actor had to gain quite a bit of weight to play "Irving Rosenfeld" in American Hustle. All the hard work paid off though, he was nominated for an Oscar in 2016.

Angelina Jolie played "Lisa Rowe" in the psychodrama Girl, Interrupted. To play a crazy person, you have to look like one, too! Crazy hair and a wild stare are just a few of the things that made Jolie nail the part. She won an Academy Award for her performance in 2000.
