The Rumor: J. August Richards will join the show, and he'll play Luke Cage!
It wasn't hard to confirm that Whedon alum J. August Richards would join the show, but once footage of his character surfaced in the trailer, speculation over who he would play was ignited. For a while, a lot of people thought that he'd be playing Luke Cage, while others believed he would be a smaller Marvel superhero, Rage. There were also reports from San Diego Comic-Con that Richards would play the minor Marvel character Mike Peterson. Whoever he is, he's definitely not Cage, as that rumor in particular was dimissed by producer Jeffrey Bell earlier this year.
The Verdict: Richards' casting is True, but the Luke Cage rumor is False
