Actor Jared Leto really isn't joking around. He recently practiced (what we think is) his best "Joker" voice while on stage at a 30 Seconds To Mars concert captured in the Vine below. He dyed his hair platinum blond earlier this month in preparation for his upcoming role in the new Batman film Suicide Squad.

Warner Bros. announced Will Smith and Margot Robbie (Wolf of Wall Street) in addition to Tom Hardy, Cara Delevigne, and Jai Courtney will join Leto in the movie.

Although it'll be hard to live up to Heath Ledger’s iconic performance, it sounds like Leto is on the right track. Suicide Squad is currently set to premiere Aug. 5, 2016.
