Back when I was told Bryan Cranston was cast as Lex Luthor for Batman Vs. Superman, I was also told Lex Luthor would be similar to a Samuel L. Jackson Nick Fury, with the character popping up in other movies.
I was also told DC is going to have all of their main characters liberally appearing or at least mentioned in all of their movies to portray a more connected world than what Marvel Studios has done so far.
Interestingly enough, now Marvel appears to be following suit as it's become known Robert Downey Jr. is also starring in Captain America 3 alongside Chris Evans.
Obviously, we got the Cranston info wrong (no one gets everything correct), but we were correct about the Justice League appearing in Batman Vs. Superman leading into the Justice League movie, and I also was the first to suggest Wonder Woman would be appearing.
Regarding Suicide Squad, it's said Will Smith, Tom Hardy and Margot Robbie are close to signing.
David Ayer is directing Suicide Squad, which has a 2016 release.
