Joaquin Phoenix ~ 52 Pounds, Method: Unknown
Joaquin Phoenix is well known for his incredible method-acting, but when he decided to lose 52 pounds just to get into character to play the part of Joker, we were shocked. Losing that much weight in such a short period of time could be dangerous, and that is why his journey was supervised medically.
For some reason, Joaquin’s exact method to shed those pounds is undisclosed, but all we know is it is so impressive. There couldn’t possibly be an actor who does more for their role than this man, and that is for sure.
