The list of contenders for the lead in Marvel’s upcoming Guardians of the Galaxy movie has gotten a bit more interesting.  We learned back in November that a number of actors were on the shortlist for the role of Star-Lord in director James Gunn’s adaptation of the comic, and just a couple of weeks ago reports surfaced that the search had been narrowed down to Jim Sturgess, Zachary Levi (Chuck), and an unnamed third actor.  Now it appears that said unnamed actor is none other than the multitalented Joseph Gordon-Levitt.  Hit the jump for more.Word of Gordon-Levitt’s involvement comes via Deadline, who report that Marvel has added JGL to the list of actors they are considering for the lead role of Peter Quill.  There’s no confirmation of whether Gordon-Levitt has been offered the role, but he’s certainly the most high-profile actor that has been mentioned thus far.  For those unaware, Peter Quill aka Star-Lord was born of a human mother and alien father, and he’s a master strategist and combat expert who wears an ability-enhancing suit and pilots a psychically-linked ship.  The character will serve as the audience’s introduction to the galactic world of Guardians of the Galaxy in Marvel’s space-set film.Gordon-Levitt is in an interesting position as his character was revealed to be Batman’s successor in Christopher Nolan’s trilogy-closing The Dark Knight Rises.  Rumors have swirled that he may be picking up the cowl as the new Batman in Warner Bros.’ Justice League film, but those reports have thus far gone unconfirmed.  Should his consideration for the Guardians gig turn out to be true, that likely means his involvement in Justice League is/always was a no-go.  The actor also has a burgeoning filmmaking career on the horizon, as his directorial debut Don Jon’s Addiction will premiere at the Sundance Film Festival in a couple of weeks.
