Just when you think Marvel has basically every big name in Hollywood, they may have secretly added one of the biggest and most iconic actors of all-time. Fresh off an Oscar nomination (that he should have won by the way), it looks like Rocky himself, Sylvester Stallone, is making his way to the MCU.

New York Daily News revealed a picture of him walking out of his hotel in Atlanta with what appears to be a script in hand.

While there are no details on what his role could be, a source close to New York Daily News said that his role is most likely a cameo. This could be the case, and if so would still be fun, but I find it odd they would give someone what appears to be a large chunk of the script for a mere cameo.

Stallone’s voice being behind Ego the Living Planet sounds like a perfect chance to get him involved, since it seems like my first choice (Al Pacino) will not be doing it. Other than that, I’m not sure what role he could play so tell us your theories. Also, with Quill being taken from Earth in 1988 and having already name dropped Kevin Bacon, it’s possible he has seen any of the first four Rocky movies which would give James Gunn a chance for a hilarious moment where Quill thinks he recognizes Stallone’s character or his voice.

Guardians of the Galaxy Vol. 2 is scheduled to hit theaters May 5, 2017.
