On his day off, Leto shipped a video message and a dead hog to set
"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,'" recounted co-star Adam Beach. After the gang played the message, one of Leto's "henchmen" dropped a dead pig on a table. "It blew our minds away," Beach said. "We realized that day: this is real." Holy hell.
Leto met with psychiatrists and emulated their most damaged patients' quirks
“You don’t know what the Joker is going to do next; you never do,” he revealed to Entertainment Weekly. “It was intoxicating to have no rules.” Jared Leto is not a guy you want to get stuck playing five hours of Monopoly with.
Leto gave everyone a dildo and a switchblade when they wrapped shooting
“The wrap gift was his fun way of getting back at all of us,” Fukuhara told EW. “I wanted to keep everything.” Warning: Suicide Squad side effects may include an inclination to method act.
He constantly gave birth to himself
Hey, director David Ayer's words, not ours. “He constantly has to give birth to himself; he goes away, he comes back, he shoots, he goes away... The Joker is something you have to be, and you can see how exhausting and painful it is for him to be this character. But you can feel it when he comes to work, the crew feels it, everyone feels it. It’s like the birds stop flying. He’s fucking terrifying.”
He acted like an animal in the dressing room
When Suicide Squad costume designer Rene Fontana first met Leto, he told her up front that he was going to "come in like the Joker." Incredibly, Fontana did not resort to violence. "Sometimes he tried to terrify us, but we’re strong women. He was growling at us, and we’d play back.”
Leto spooked random city folk with his Joker cackle
“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 laughs would get under people’s skin,” Leto told Squawk Box. He's right, really -- if a maniacal laugh can freak out a New Yorker, it belongs in Suicide Squad.
Leto claimed responsibility for the cast's worst memories
During rehearsals, Ayer asked each actor to recall the dark moments in their lives. “We all shared really deep stories about ourselves and our pains and our triumphs,” Smith said at Suicide Squad's San Diego Comic-Con panel. “And then on set you thought he was being a nice guy you were trying to share your life, and then in the middle of a scene he throws your childhood trauma back at you and says, ‘Dude, the Joker did it.'”
