Leto introduced himself to the comic book movie's star-studded cast by mailing them part of a dead swine, while he also sent a black rat in a box to Margot Robbie, who stars as Hayley Quinn.

Jared's co-star Viola Davis, who plays a government agent in charge of the squad, told Vanity Fair magazine: "The henchman came in with a dead pig and plopped it on the table and then he walked out. And that was our introduction to Jared Leto.

"Now I'm terrified just as a person thinking 'Is he crazy?' But the second part was, 'Oh s**t, I've got to have my stuff together'.

"You talk about commitment. And then he sends Margot Robbie a black rat, that was still alive in a box. She screamed, and then she kept it."

Meanwhile, it was revealed last year that Will Smith, who also stars in the movie, staged a gig for the cast of the film.

The much-anticipated new flick also features model-turned-actress Cara Delevingne, who portrays sorceress Enchantress.
