I wonder if this will lead into the Heroes for Hire showing up on the show.
Hopefully it will lead to an actual Heroes For Hire show. But that's getting way ahead of ourselves.
Maybe he's not playing anyone famous? He could be a new character or even a sleeper agent?
Gotta be Patriot. Way too small to be Luke Cage...
EDIT: In fact, I'm actually rather excited at the prospect of him being Patriot. Not sure how they'll have him get his powers, but it would be great if he has this enormous respect and admiration for Captain America (hence why he calls himself Patriot)...which could even make for an interesting relationship between him and Coulson, who is of course a Cap-fan himself!
Just keep in mind that Cage was always planned for TV (and thus a TV actor) even way back when the Jessica Jones series was being planned. Also, on the Marvel montage, it's the same exact montage from the Avengers movie, and other MCU films as well. It does not indicate content like the special ones they make for FF, Spider-Man and sometimes Iron Man.
It's probably Cage, a somewhat solo character that's not likely to get a movie, but still has a lot of appeal rather than Rage, an always team character that has zero public appeal. Plus, there's enough to deal with figuring out the explosion and who this guy is, you don't wanna have to deal with a 30 year old man with the mind of a 13 year old.
And I love Patriot... but Patriot can't do that...
And again: The same exact Marvel intro logo shows in front of Avengers and other MCU films, clearly. It's not a content indicator like the modified ones for Spidey or Iron Man. It's just the standard Marvel bumper now, created when the series was just a faint dream in the back of Whedon's head. This was pointed out immediately when someone posted this discovery to Twitter.
Good point, that Luke Cage has been mentioned for movies before. The most recent stuff is for TV though, and there's no indication that they've gone back to prospects of making a movie for him. Notice he didn't come up in the recent potential MCU films announcement - probably because he's no longer a potential film. So either they have TV plans for him, or none at all.
