We can't think of a better way to kick off the weekend than with a bloody red band trailer for Hansel and Gretel: Witch Hunters. Jeremy Renner and Gemma Arterton portray the title characters in this adventure, set 15 years after their incident at the gingerbread house. Now they are all grown up, hunting down witches and other demons. Take a look at the latest footage from director Tommy Wirkola's action-thriller in this age-restricted trailer, which features R-rated language.
