To see rear projection used in American films, you should watch the films of Ã‚Â Douglas Sirk (Written on the Wind, Magnificent Obsession, Imitation of Life). He used false backgrounds in his films before any of the French New Wave guys did. Also rear projection can be seen in many B films from the 40s and 50s. Note : QT pays tribute to Sirk in PF, with the Jackrabbit Slims scene where Vincent orders the “Douglas Sirk steak”.
QT used rear projection in a couple scenes in Pulp Fiction. For instance the scene where John Travolta is driving to pick up Mia Wallace. The cab ride when Butch is talking with Esmerelda Villalobos.
