The Disgusting Gifts Jared Leto Sent His 'Suicide Squad' Co-Stars What live creatures he sent Margot Robbie and others.

 -- Jared Leto is known to go method for some roles, but this takes the cake.

The Oscar winner, 43, is playing the legendary Batman villain The Joker in "Suicide Squad" and his co-star said he sent some disgusting gifts to the likes of Margot Robbie and Will Smith, who also star in the film.

"He sent [Margot Robbie] a nice love letter with a black box with a rat in it — a live rat," Adam Beach, who plays Christopher Weiss, aka Slipnot, in the movie, told E! News. "It was beautiful. Then he sent bullets to Will [Smith] with a letter."

He also sent the cast a dead hog and a video.

Leto sent these gifts not only to gross them out and get into character, but because he wasn't there early on in the filming process.

"Basically, what he said was, 'Guys, I can't be there but I want you to know I'm doing my work as hard as you guys,'" Beach said. "The video he showed is in character. It blew our minds away. Then we realized that day, this is real. ... He encompasses this beautiful man and he shows it in, 'Hello, how are you?' but in an instant, he goes to psychotic behavior where you're in fear."

"Suicide Squad" is scheduled to hit theaters Aug. 5, 2016.
