Can you say "comic relief"?
Variety reports that on-the-rise comic actor Charlie Day is in talks to join Guillermo Del Toro's mega monster movie "Pacific Rim." Of course, many people already know Day from his work on "It's Always Sunny in Philadelphia" but he's making his mark in movies too, stealing scenes handily in the otherwise tepid "Going The Distance" and getting ready to earn more laughs with his turn in the upcoming "Horrible Bosses." No other details on his role, except that he will be playing a (probably hilarious) professor.
Day joins the already cast Charlie Hunnam, who is set to play Raleigh Antrobus, who along with his brother, pilot Jaegers, enormous building-sized robots constructed to fight off the malevolent creatures, driven telepathically by a pair of specially-trained pilots, working in tandem. Idris Elba was recently said to be sought out for a role (but he's also weighing "Django Unchained"), with Alexander Skarsgard apparently turning down the film due to his commitments to "True Blood."
Production on the film get underway this fall; no release date has been set.
