Like Machete, Jason Eisner’s film began life as a faux trailer for Tarantino and Rodriguez’s Grindhouse. It was a fan-made piece that won a contest and was included with some theatrical showings of the film, but not all of them — which explains why you might not have seen it.
Actor David Brunt played the hobo in the original, but for the feature Hauer stepped into the part. Don’t feel bad for Brunt, though — he’s got another role in the feature length version.
