That's how you know it's a bullshit rumor, but goddamn would it be great to have him as Manta. I like his presence.Mahershala Ali as Black Manta would be the shit for sure.
I have to admit Dan Trachtenberg as the director of Flash would be a bold choice. He's the kind of guy that could inject the youth WB is looking for in the film. Don't know if he's ready for this kinda movie though. But I am so down if the rumor is true.
