Michael Rosenbaum Is In Guardians of the Galaxy Vol. 2!

Speaking on The Adam Corolla Show, director James Gunn revealed that his longtime friend Michael Rosenbaum – that’s Smallville’s Lex Luthor to you – is in Marvel’s upcoming film Guardians of the Galaxy Vol. 2!

“We do have a couple of characters who are very important to the Marvel Universe who are going to make their debut in Guardians of the Galaxy Vol. 2 which people don’t know about,” Gunn said on the show. “Sylvester Stallone plays one of these characters…my friend Michael Rosenbaum also has a pretty decent movie in the role as well and it sort of works in tandem with Sly’s character.”

Who is Michael playing? That, we don’t know… but still, cool, eh?
