Lee Pace, currently playing Thranduil in the Hobbit films, has been cast as the villain in the upcoming Guardians of the Galaxy film. No word yet on who he will be playing, however rumor has it he will be playing someone known as Taneleer Tivan, the Collector.
In the comics, Tivan learned about the threat Thanos posed to the universe and sought to collect life forms and worlds to place in a museum of sorts, ideally protecting them from Thanos’ path of destruction. You may recall this being a theme from the Halo games as well, with the Librarian seeking to index life for preservation.
He will be joining Chris Pratt, Dave Bautista, Zoe Saldana, Michael Rooker, and Ophelia Lovibond in the film directed by James Gunn and released August 1, 2014.
