I was scrolling through Facebook this morning and found this video posted by a friend. It's a short film directed Matthew Ross called "Inspired by Brett Easton Ellis". This is a very snappy little 3-minute summary of the Ellis-verse starring some actual celebrities too....Kip Pardue and James Van Der Beek. If you've read only "Less Than Zero", you'll get the basic idea. If you haven't, a word of warning that this is a bit NSFW.
