A while back, Common was suppose to star in a Justice League movie as John Stewart AKA Green Lantern. The movie was already in production when it canceled. It got canceled for 2 reasons. 1 Chris Nolan didn't want a JL movie to have Batman songs he was in the middle of his Batman series and 2 the writers strike. Common said the following recently:
"I remember a time I really struggled with showing gratitude. It was after I had been cast as the Green Lantern in the movie rendition of “Justice League.” We were all set to go. We had even tried on our wardrobe. I was ready! I was imagining what this could not only mean for me but also for the kids who would see me as a bona fide superhero! Plus, my phone was already ringing off the hook with requests for meetings from big-time directors and producers. It was about to be on…
And then it happened — the writers’ strike. Everything was on hold and after the strike, executives pulled the plug on the production. I was deflated. What I thought was the biggest role in my life was gone — just like that. I moped around for a few days when finally my mom told me to “get over it” and go speak to an organization that helped kids with much bigger problems than mine. It was during my talk with those young people that I had to take stock in what I had and return to being thankful for everything."
Personally I still hope Common gets to play GL.
