Don't

Video Nasties-style Britsploitation Screamer Trailer directed by Edgar Wright, with Simon Pegg, Nick Frost, Matthew McFadyen, Mark Gatiss, Jason Isaacs and narration by Will Arnett. The main joke of the trailer is that it's the American trailer for a British horror film, and the distributors, in order to prevent the audience from finding out that it's British, have cut the trailer so that none of the characters are heard speaking and we get no idea of the plot. The title is a reference to American International Pictures' releases of British or European horror films under "snazzier" titles - specifically, a film whose Spanish and Italian titles translate to I Do Not Profane the Sleep of the Dead, but was released in the USA as Don't Open the Window! even though there's no particular emphasis on windows in the film.
