RODRIGUEZ: Well, that one was one I was thinking of doing before
Sin City; I had an idea to do a double feature. I had an old double feature poster that had two movie posters on the same poster, saying 'Two Hot Rod Flicks Together,'
Drag Strip Girl and
Rock All Night or something like that, and I thought I should do something like that; they are truncated features, like each one is an hour. I forgot about it and went to show [Tarantino] his
Sin City scene, and he had the same poster on his floor (laughs). I said, 'Hey! I was thinking about doing a double feature - you should do one and I'll do the other one.' He was like, 'Oh, f*** yeah, we'll call it
Grind House and we'll do fake trailers in between for movies that don't exist.'
