I can confirm that John C. Reilly will play Ronan The Accuser Dey in Marvel Studios Guardians Of The Galaxy, the James Gunn-directed franchise launch that stars Benicio Del Toro, Glenn Close, Chris Pratt, Zoe Saldana, Lee Pace, and Michael Rooker. Ronan comes from the planet Hala in the Kree Empire, and he is the Kree equivalent as the badass-inest juror and military governor in space.
He first surfaced in the Marvel Comics in Fantastic Four, as a bad guy, and he possesses superhuman strength, endurance, speed and reflexes, shielded by an exoskeleton armor suit can make him invisible. He also wields the universal weapon, which looks like Thors hammer, only cooler. The other intriguing thing about Ronan is that in some versions of the comics, he is the son of Thanos, also known as the Avatar of Death. Thanos has been incorporated into The Avengers and will be in Guardians Of The Galaxy. That is an easy way to mix the two franchises and allow the characters to show up in all different Marvel movies, so dont be surprised if Reilly becomes a staple of Marvel Studios fare.
