While we've already seen two different trailers for Warner Bros.' Suicide Squad, we still haven't seen much of Jared Leto's The Joker, who has only surfaced in bits and pieces of footage released thus far. Jared Leto's off-screen antics while getting into character are already the stuff of legend, with the actor sending bizarre gifts to his cast members, while never breaking character throughout the production, even between takes. Today we have some more insight into the actor's process in a new interview where Leto reveals how he honed his iconic Joker laugh for the movie.

Before production began last spring, the actor was touring with his hit rock band 30 Seconds to Mars, and videos surfaced of the actor practicing his Joker voice with the crowd. As it turns out, Jared Leto also practiced his iconic laugh with random passers-by on the streets of New York and Toronto, where filming took place last year. During a new interview on CNBC's Squawk Box, via YouTube, the actor reveals his unique process for testing out his diabolical laugh.

"I worked on the laugh walking around the streets of New York and Toronto, and I kinda would walk around the streets and see what laugh would get under people's skin. You know when you hear someone laugh at a restaurant? It's a little jarring. I tried them out. And I kind of got to a place where I would laugh and people are always turning around like, 'Who is this creepy guy behind me?'"

This revelation comes just weeks after Jared Leto revealed in a separate interview that he met with experts, doctors, and psychiatrists that dealt with psychopaths, and he also met with some actual deranged killers who had been institutionalized for their violent crimes. We recently reported that reshoots took place, rumored to add more humor. But it isn't known if Jared Leto was present for these additional scenes or not. It has been hinted that he spends much of the movie in a jail cell, though he plays a pivotal role in a massive prison riot during the third act.

Suicide Squad hits theaters August 5, going up against The Weinstein Company's The Founder and EuropaCorp's Nine Lives. David Ayer is directing from his own screenplay, and there are rumors that the studio wants the director and the main cast to come back for Suicide Squad 2, which would reportedly start shooting next year, and have an R rating. Those details haven't been confirmed yet, so stay tuned for more on Suicide Squad and Suicide Squad 2. Take a look at the excerpt from Jared Leto's CNBC interview where he talks about his Joker transformation below.
