James Gunn has revealed that Smallville actor Michael Rosenbaum will play a significant role in Guardians of the Galaxy Vol. 2 (out May 5). Gunn also teased the characters played by both Rosenbaum and Sylvester Stallone. The director made the announcement during an appearance on The Adam Carolla Show podcast.

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

Rosenbaum subsequently tweeted about Gunn’s announcement. “I kept yapper shut 4 a year but can finally say what James Gunn announced on Adam Carolla,” he wrote. “I’m in freaking Guardians.”

Rosenbaum played Lex Luthor on Smallville and previously worked with the Guardians director on James Gunn’s PG Porn, a web series created by Gunn and his two brothers, Sean and Brian.

Guardians of the Galaxy Vol. 2 is released May 5.
