Oscar-winning actor Benicio del Toro is the latest addition to Marvel Studios' Guardians of the Galaxy cast, according to Deadline.
His part is currently unspecified, but Deadline calls it a "lead role," and says he's "playing a character that is built to be part of future Marvel films," and has thus signed a multi-picture deal.
With most of the lead Guardian roles already cast — Chris Pratt as Star-Lord, Zoe Saldana as Gamora and Dave Bautista as Drax the Destroyer — it's possible del Toro could be another major Marvel hero (Newsarama's David Pepose suggested Black Bolt of the Inhumans) or the film's main villain, perhaps a motion-capture Thanos (first glimpsed in the mid-credits scene of last year's Avengers, then played by Damion Poitier). Lee Pace and Karen Gillan have both been reported to also be playing villainous roles.
This wouldn't be the first comic book movie for del Toro, who played Jackie Boy in 2005's Sin City adaptation. He won Best Supporting Actor at both the Academy Awards and Golden Globes for his role in 2000's Traffic.
Del Toro is joining fellow recently reported cast additions Gillan and Glenn Close, whose roles have also yet to be named. Guardians of the Galaxy, written and directed by James Gunn and also starring Michael Rooker as Yondu, is scheduled for release on Aug. 1, 2014.
