Suicide Squad director David Ayer has hired a "therapist" to stop his cast going too far in their roles.
The filmmaker is keen for his actors, which include Adam Beach as Slipknot, Jared Leto as The Joker, Will Smith as Deadshot and Margot Robbie as Harley Quinn, to be "tormented" during shooting of the movie, but he doesn't want them getting too "villainous".
Adam told E!: "David Ayer is about realism. So if your character is tormented, he wants you to torment yourself. He wants the real thing.
"We kind of have like a therapist on board if you fall off the wagon and really are villainous.
"There's a friend of [Ayer's] that's very unique in making sure we have our ground."
