Irving Rosenfeld – Christian Bale
It's time to talk about another method actor! Similar to Jared Leto and Gary Oldman, actor Christian Bale completely immerses himself in his roles. This entails undergoing significant physical transformations, such as losing or gaining weight, and even adopting his characters' accents for extended periods.
For his portrayal of con artist Irving Rosenfeld in the 2013 film American Hustle, the renowned English actor gained a staggering 43 pounds. He has described his approach, saying, "I indulged in countless doughnuts, an abundance of cheeseburgers, and whatever food I could lay my hands on. I literally consumed anything that came my way."
