John C. Reilly has been confirmed as Rhomann Dey in Marvel’s Guardians of the Galaxy, according to Deadline.  In the comics, Dey was the leader of the Nova Corps who transferred his power to Nova on Earth.  In the film, as we previously reported when Reilly's name first surfaced, he may be more of an Agent-Coulson-style liaison between the Guardians and S.H.I.E.L.D. while Glenn Close plays the head of the Nova Corps (see "Glenn Close Joins 'Guardians' Cast" and "Ruffalo Signed for ‘Avengers 2'").

Reilly is the latest in a string of high profile actors cast in the film; he follows Benicio Del Toro, who was recently cast in a yet-to-be-announced role (see "Benicio Del Toro in 'Guardians'"). 

The film is being directed by James Gunn and will be released August 1, 2014.
