We learn a tidbit about the Suicide Squad in that Jared Leto stayed completely in character as Joker during filming -- so much so that Leto never even spoke to Will Smith as the two worked on the film together for six months.
Will Smith told Complex the following:
[Suicide Squad] is insane. I've never actually met Jared Leto. We worked together for 6 months and we've never exchanged a word outside of 'Action!' and 'Cut!' I literally have not met him yet. So, the first time I see him will be 'Hey, Jared. What's up?' He was all in on the Joker.
For fans of Smith's Bad Boys series, the actor is currently involved in a third film and offered up the next one should be coming out in 12-16 months.
"Suicide Squad" has an August 5, 2016 release date directed by David Ayer starring Will Smith as Deadshot, Jared Leto as the Joker, Margot Robbie as Harley Quinn, Cara Delevingne as Enchantress, Jai Courtney as Boomerang, Joel Kinnaman as Rick Flag, Viola Davis as Amanda Waller, Adam Beach as Slipknot, Karen Fukuhara as Katana, Adewale Akinnuoye-Agbaje as Killer Croc, Jay Hernandez as El Diablo, and Scott Eastwood in an unknown role.
