The stars of Guillermo Del Toro's Pacific Rim are clearly going to be the colossal mecha and the director himself, but that's not to say that the cast won't be filled with intriguing choices. Idris Elba and Charlie Hunnam are already thought to be attached, and they now look set to be joined by Charlie Day, when Del Toro's cameras start rolling in the autumn.
Day, like his fellow Charlie (Hunnam is a staple of Sons of Anarchy) has been plucked from the small screen where he's an amiable fixture of It's Always Sunny in Philadelphia. He's turned his success in that show into roles in Going the Distance and Horrible Bosses, but it's fairly safe to say neither will have prepared him for battling extraterrestrials in an iron giant. Still, his character is apparently some sort of professor, so if he's only inventing the robots, maybe he won't have to.
Pacific Rim, if you're late to this party, is where Del Toro landed after the collapse of At the Mountains of Madness. Incredibly, thanks to all the Hobbit and Lovecraft shenanigans, it'll be his first directorial gig since Hellboy 2 three years ago, so he'll be enjoying a feeling of 'f**inally!' when shooting starts in September.
Don't Be Afraid of the Dark, which Del Toro co-wrote and produced, is out in the UK on August 12.
