'The 3rd Floor': 'The Office' Teases Online Halloween Horror Flick (VIDEO)

It looks like "The Office" is planning more than a traditional Halloween episode this season. On Oct. 28, Ryan Howard's horror movie "The 3rd Floor" will premiere online, and from the looks of the trailer below it's going to be pretty awesome.

Starring fellow co-workers Erin, Kelly, Meredith, Kevin and more, "The 3rd Floor" looks like your standard slasher movie, except that it takes place in the beloved Dunder Mifflin offices (on the third floor). We don't want to give anything away, but it looks like sweet, little Erin is the one doing most of the slashing. Interesting choice, Ryan!

If the show's other webisodes such as "Subtle Sexuality" are any indication, "The 3rd Floor" should be a fun watch right before Halloween, if only to see Kevin with that hilarious fake mustache.
