UPDATED (AUG. 30, 2013): Marvel Studios has had a habit of occasionally casting out-of-the-box actors for its movies. Kat Dennings in Thor and Robert Redford in 2014's Captain America: The Winter Soldier aren't the sort of actors one might expect to see in a comic book movie. Most famously, pre-Iron Man Robert Downey, Jr. was a quirky character actor with zero box office cred.
With Guardians of the Galaxy, however, co-writer-director James Gunn (Slither) has apparently been given carte blanche to cast his movie pretty much entirely with actors you would never expect to see in a modern comic book movie — or, at least, never in the way he's cast them. With each new casting notice, this movie — which started production in July — just gets more and more koo-koo-brains exciting.
