It has been quite obvious that Jared Leto got a little crazy while on the set of 'Suicide Squad.' The Oscar winner went out of his way to send his costars a few presents that only The Joker would send, including a live rat for Margot Robbie.

But just how disturbing is Jared Leto's performance as the Joker in 'Suicide Squad?'

The 43-year-old actor was recently at the Dubai Music Week with his band 30 Seconds to Mars. During a Q&A before the band's performance, Jared Leto noticed that someone showed up wearing a Batman Tshirt. According to The National, the singer pointed the man out and teased the audience about his performance.

"And to the wise-guy who turned up in a Batman shirt? 'You're really brave,' deadpanned Leto, before letting out a deranged laugh, referencing his upcoming role as The Joker in Suicide Squad. 'I can't wait for you to see this - they're going to lock me away in a box after this movie comes out.'"

His character might be a sociopath, Jared Leto is obviously someone who wants to change the world in a good way. The 30 Seconds to Mars frontman also admitted that he loves the Middle East and wants the rest of the world to understand it.

"I would love to do a special tour of the Middle East and make a film about it - that would be awesome," he said. "America and the Middle East have a very complicated relationship, but underneath all that we have so much in common. It's just such a waste of energy for people and governments to continue to fight about stupid things, it's so ridiculous. Selfishly, I would love to come and visit some of these places."

'Suicide Squad' is directed by David Ayer and will be released on August 5, 2016.
