Leto did the craziest things for the role

I guess you’ve already heard of some things the actor did to get into the character’s skin. One of them was totally ignoring Will Smith and not talking to him except for the times when they shot scenes together. Will Smith was shocked, and told Apple Beats 1 Radio:

[Suicide Squad] is insane. I’ve never actually met Jared Leto. We worked together for six months and we’ve never exchanged a word outside of “Action!” and “Cut!” We’ve never said “Hello” or “Good day”. I’ve only ever spoken to him with me as Deadshot and him as The Joker. I literally have not met him yet. So, the first time I see him will be “Hey, Jared. What’s up?” Not a single word exchanged off-camera. He was all in on the Joker.

It’s obvious that Jared worked hard for the role, his talent is undeniable, and his version of The Joker is good!
