The movie is best known for its re-use of footage from other movies. Roger Corman offered to let Dante make a movie if he could keep the budget very low. Dante achieved this by writing a script about a B-movie studio where he could shoot plot scenes cheaply with the actors and intercut them with action sequences from other movies that Corman owned, such as Death Race 2000. Although this wasn't an unusual technique for low-budget movies of the era, Hollywood Boulevard took it to extremes.
Several key people in the crew went on to bigger careers, from director Joe Dante, Gremlins, to art director Jonathan Demme, Silence Of The Lambs. Hollywood Boulevard would end up grossing upwards of a million dollars, not a bad return on a $25,000 budget. Hobgoblins director Rick Sloane credits this movie as the inspiration for his film making style.
