Here's the trailer for Hansel and Gretel: Witch Hunters, the upcoming action-comedy starring Jeremy Renner and Gemma Arterton as the iconic siblings. The pair — having defeated the witch who made that awesome candy house — are now all grown up and making their livings by hunting down witches. Sure, it looks like a major cheese fest, but take a couple of hits from the ol' bong before you go to the theater and Hansel and Gretel: Witch Hunters could be the best the film you see all year.
