Remember back in June, Fast and Furious star Vin Diesel was all sly and like “Hey, Marvel requested a meeting with me, I have no idea why”? Then in July after he went down to the Marvel offices and had said meeting, he posted to his Facebook page, “Marvel meeting today”¦ Only the people in the room can tell you what was discussed”¦,” which was accompanied by a photo of the actor standing in front of a framed poster of the Avengers #2 comic book cover. Remember that?

It’s likely that Diesel will indeed appear in a Marvel movie (otherwise, how embarrassing for him!). But for some bizarre reason, whatever role he’s playing is such a secret he can only tease his fans about it. Early speculation was that he’d be playing Vision in The Avengers 2, but on Sunday the actor posted a picture from a comic book panel on his facebook page solely of Groot, the tree-like humanoid from Guardians Of The Galaxy. No caption came along with the photo, which was put up as Diesel’s FB cover photo for a little while, before it was changed (though the photo is still on FB).
