We’re starting to write about Charlie Day so often, it might be time for him to get his own PopWatch category. Feel free to nominate a name for it in the comments section. Like Skarsgard Your Loins, our reader-suggested category for Alexander Skarsagard, it should have his name in it somehow. Today’s news: Variety reports that the It’s Always Sunny in Philadelphia star (and Going the Distance and Horrible Bosses scene-stealer) is in talks to join Guillermo del Toro’s alien invasion flick Pacific Rim. Per the trade, Day would play a professor, and the filmmakers, who have already tapped Sons of Anarchy‘s Charlie Hunnam, are looking to cast more rising talent. There’s no word on whether Day is the comic relief, but I’m hoping for a Jeff Goldblum in Independence Day-vibe. You?
