Sure, I've got my issues with the guy, but even I'm willing to admit that, at his peak, Harlan Ellison wrote some of the best short stories in 20th-century American literature, so I'm totally excited to see the trailer for Dreams With Sharp Teeth, a profile documentary that's been in the works for over 25 years and looks like it might be as entertaining as the Sam Fuller profile The Typewriter, the Rifle, and the Movie Camera, which I love. Just be warned: In addition to appearances by Neil Gaiman and Robin Williams, this trailer also includes quite a bit of NSFW language.
