A wholly enjoyable bit of self-indulgence, Studio 666 is an odd little movie. On the one hand, it’s a campy horror/comedy with an overflow of silly gore. On the other hand, it serves as a promotional vanity project for a legendary rock band that doesn’t need it. The “haunted mansion” concept is also paper-thin, and you can bet your butt that you will know exactly how it’s all going to play out from the get-go. It’s the over-the-top shenanigans that keeps thing interesting, as there is undeniable fun to be had with the exceedingly bloody proceedings. And for those wondering how the Foo Fighters fare as actors, well, this critic gives them a passing grade. No one should be expecting Daniel Day-Lewis levels of acting feats though. What they do bring to the table, however, is a heightened energy and a willingness to embrace the bizarre. And with Grohl doing most of the heavy lifting, he’s more than effective in the leading role (this movie did come from his twisted brain after all). Unfortunately, the film has an ending problem. At 1 hour and 48 minutes, it meanders way past the point of “time to wrap it up.” It’s rather ironic as one of the plot points has to do with finding a way to end an overlong song. But don’t worry, if you are going in for the music, there’s plenty of head-banging riffs. Yes, Foo fanatics will no doubt be happy to spend this time with their fave bandmates. Horror-comedy fans should also get a kick out of the icky bloodshed and genre homages. I’m just not sure either will be screaming for an encore.
