As well as playing a drug addict in 2000’s ‘Requiem For A Dream,’ the 43-year-old star also gained a considerable amount of weight, 60 pounds to be exact, to play John Lennon's assassin, Mark David Chapman, in 2007's ‘Chapter 27.’

Leto is planning on gaining weight once again to portray the Joker in the upcoming superhero flick ‘Suicide Squad,’ which will hit theatres on August 5th, 2016, and while speaking to Billboard magazine, he revealed his plans to eat as much as he can.

"Do you mind if I eat a little?" the actor asked in Billboard's Feb. 28 issue. "I'm trying to gain a lot of weight. It means I have to eat every couple of hours—and I'm terrible at eating a lot."

Leto is now in a very talented and exclusive group of actors who have played the Joker, including Jack Nicholson in Tim Burton's ‘Batman’ (1989) and Heath Ledger in Christopher Nolan's ‘The Dark Knight’ (2008), so when this opportunity came up, he just couldn’t say no.

As well as Leto, starring roles in ‘Suicide Squad’ have also been given to Will Smith and Tom Hardy.
