Like any good hero, you can't keep Riddick down. The people keeping the star of Pitch Black and The Chronicles in Riddick chained up in this latest trailer for Riddick discover that pretty quickly as their supposed safehouse turns into a smorgasbord for whatever creepy crawly aliens lie in wait outside. Be warned, the trailer does feature the deaths of several characters, including at least one that's a step above the usual sci-fi cannon fodder.

The latest film in David Twohy's sci-fi franchise finds fugitive Riddick setting off a beacon in order to get off a planet that happens to be filled with alien predators. Not knowing what they're getting themselves into, two different groups of bounty hunters and mercenaries descend on the planet in an attempt to capture the anti-hero.

Opening Sept. 6,  Riddick stars Vin Diesel, Katee Sackhoff, Dave Bautista, Karl Urban, Jordi Mollà and Bokeem Woodbine.
