'84 Raleigh USA machines, for the most part.
Casey's is most obviously an fixied/singlespeeded (depending on the scene) '84 Comp, sometimes decked out with a straight blade trick fork as most obvious in some scenes. Get a close look at the reverse-mounted brake with a dissapearing brake cable in the thrift shop window sillouette scene. Messenger in the opening scenes rides a stock '84 Grand Prix. One fixie rider in the opening titles has what appears to be a 1985 Super Course.
Voodoo has what I believe is a Nottingham-built '83 machine which sports the same build qualities (Raleigh logos on seatstay caps, etc.) and chromed rear trangle, front fork and headtube as the Japanese '84s, but features translucent green paint. I've never seen this model in a catalogue, or even heard of a forum member owning one - but a semi-regular at the LBS owns one with semi-translucent burnt orange metallic. Doesn't have any name on the frame. As for Voodoo's example in the movie, we get to see far too little of it. All I can make out is an Ofmega or SR copy aero-type crankset - most likely the Ofmega, considering the '84 Raleigh Prestige used the high-polish Ofmega over the SR.
Lots of cheapo machines were used for the "extras." Couldn't even figure out what most of them were.
