Just hours after Deadline reported that Marvel has Joseph Gordon-Levitt on their radar as one of the (many) contenders in contention for the lead role in Guardians of the Galaxy, another actor with familiar to comic book adaptations announces he’s in the running as well.

Michael Rosenbaum, known for playing Lex Luthor for many seasons of the CW’s Smallville and for his voicework in multiple animated DC Comics series and features, joins Levitt as another potential candidate for the part of Star-Lord (Peter Quill).

Rosenbaum, who coincidentally also shares a DC Comics background, revealed through his Twitter account that he read for the Peter Quill character, thanking director James Gunn and Marvel for the opportunity.

Believe it or not, behind-the-scenes at Screen Rant, we previously discussed the idea of Rosenbaum joining Guardians of the Galaxy in a voice capacity. Like Michael Rooker (The Walking Dead) – who’s very open to the idea of playing Rocket Raccoon – Rosenbaum is friends with James Gunn who’s rewriting and directing the film. It’s evident that Gunn likes to involve his friends with his projects, and this particular one happens to involve two central characters (among many other aliens) who will likely be realized using CG animation (Groot & Rocket Raccoon). That being said, we didn’t expect Rosenbaum to read for the lead role in space-faring team-up, which brings us to another interesting discussion point.

Since the initial Star-Lord shortlist broke a month ago, several of the candidates have since signed on to other projects (e.g. Eddie Redmayne, Joel Edgerton), while others may unknowingly be reading for different parts. Tom Hiddleston, for example, read for the role of Thor before becoming the fan-favorite Loki. Guardians of the Galaxy will boast a large roster of never-before-seen characters and not just on the core team, but in the supporting cast and villain(s). It’s very possible some of the names we’ve heard as of late could still be a part of Marvel’s future, just not as Star-Lord.

Some of the candidates reported over the last few weeks were on our own recommendations for the Ant-Man role for instance, and if that character is to make a cameo/guest introduction in one of the upcoming Phase Two films (see: Iron Man 3 rumors), that’s a character some of the talent may be reading for.

In Marvel Comics, the Peter Quill character is born half-human, half-alien due to some unusual circumstances. He grows up and joins NASA, where he earns (steals?) an opportunity to become the space cop Star-Lord. After various intergalactic conflicts, Quill forms the Guardians of the Galaxy to prevent further wars, often crossing paths with Thanos – who we know will have some role to play in the film and The Avengers 2, a year later. If you’re interested in learning more, I recommend reading Annihilation and then Annihilation: Conquest – these lead to the formation of the Guardians and their ongoing series that began in 2008.

Is Rosenbaum a good choice for the role of Star-Lord or should he play another Marvel character? To recap, Joel Edgerton, Jack Huston, Jim Sturgess, Lee Pace, Eddie Redmayne, Garrett Hedlund, James Marsden, Sullivan Stapleton, Joseph Gordon-Levitt and Zachary Levi have all been name-dropped as well in association with Guardians.
