Jared Leto's crazy behavior and odd presents were much documented during filming on the forthcoming Suicide Squad adaptation from WB and David Ayer. However, we now have a first-hand account from one of the actors on set, Ike Barinholtz. Here's a first-hand account of how Leto, who remained in character as the Joker during filming, interacted with his fellow cast members when the cameras stopped rolling.
"He did this crazy thing...all the actors were rehearsing, and his character is in love with Margot Robbie -- she's Harley Quinn...so we're rehearsing, and this actor who plays the Joker's kind of lieutenant, walks in and he goes, 'Present for Ms. Quinn.' Hands her a box. She opens the box, and a live, giant black rat pops out," Barinholtz explained to Howard Stern. "And we're like, 'What the f--k is going on? That's crazy!' So 20 minutes later, we're still rehearsing, and the actor comes back in and he goes, 'This is for the squad from Mr. J.' And he throws a pig on the table, a dead pig, and as he puts the pig on the table all these bullets start to come out of it...this is in a rehearsal space a month before we started shooting."

You have to be impressed by the lengths Leto is willing to go in order to capture the essence of the Clown Prince of Crime. Will he truly deliver a performance that's equal to stellar portrayals by Heath Ledger and Jack Nicholson? Time will tell.
