Jared is taking a break from his music following his Oscar-winning performance in Dallas Buyers Club
In developing his take on the iconic DC Comics villain, Mr Leto said: "We discussed David Bowie a bit, not necessarily the music of David, but his class, his elegance, his timelessness"
"(I met) people that were experts, doctors, psychiatrists that dealt with psychopaths and people who had committed horrendous crimes. I spent some time with those people themselves, people who have been institutionalised," said Jared Leto
The new trailer showcases Will Smith as gunman Deadshot, Margot Robbie as the crazed and provocative Harley Quinn, Joel Kinnaman as soldier Rick Flag, Jay Hernandez as scarred villain El Diablo, Jai Courtney's Boomerang and Jared Leto's much-anticipated Joker
