Just wanted to pass along this Suicide Squad tidbit in case you missed it. Apparently, Jared Leto tried to give himself the nickname of "Mr. J" while he was filming the movie. Of course, Jared plays The Joker in the 2016 DC film, and from all accounts he got deep into the part. The producer of Suicide Squad said Jared's antics on the set were "...very entertaining."
Vulture has the rest of the story below.
