While speaking with Zane Lowe on Beats 1, actor Will Smith declared that despite working with Jared Leto for half a year on the set of Suicide Squad, he still has yet to actually meet him, (via IGN). “We worked together for six 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.”

While filming, Leto took on the strenuous role of method acting, which is a technique where actors and actresses alike re-imagine themselves with the thoughts and emotions of their character.

Suicide Squad is set to release on August 5, 2016 and stars Leto, Smith, Margot Robbie, Jai Courtney, Ben Affleck and more. You can watch the first trailer below.
