This is the teaser trailer for Quentin Tarantino's The Hateful Eight, the movie whose script leaked, was cancelled, was planned to be released as a book, and then uncanceled.
Update: I'm getting emails and tweets saying this trailer is fake. And if it is fake, is there a non-fake leaked trailer out there or...?
Update: Just to be clear, this is totally fake and constructed from bits of other movies, etc.
