CBM posted this rumor and also pointed out that in April, someone on Twitter suggested Dwayne for John Stewart in a DC movie, and he responded "Funny U should say that" on his Twitter account.
However, this could have just been a hint from Dwayne that he was in talks for a DC project; not necessarily John Stewart.
