10 Biggest Justice League Mysteries

4. Is Colin Farrell Playing A Mystery Role?

Awhile back there were reports Colin Farrell had signed onto Justice League for a mystery role, which would likely just be a cameo. Naturally, DC wasn't going to confirm this if his part is meant to be a surprise, but it has lead to all kinds of wonderful speculation.

Maybe he’s playing a secret villain – Darkseid maybe? – or a superhero who will appear somewhere down the line. The most likely theory is he’ll be playing John Constantine, who will appear to set up a Justice League Dark film. Farrell is damn near perfect casting for the role, and it would be a better fit for him than a superhero costume.

Or maybe he’s reprising his role as Bullseye from Daredevil, and Justice League will set up future crossover events with Marvel? Call me crazy, but that one sounds the least likely.
