Roma 79: Film made by director Marco Zamboni in 1976 that featured Derek dressed completely in white, playing a trained assassin who is gunned down by the films protagonist before the opening credits. Other Zamboni films include "I Siciliani," "Swarthy Like Me," and "Fusilli For Two." Marty DiBergi filmed scenes in which Derek showed a Beta video of his role in the film on the tour bus, but they were cut from the final version of "This is Spinal Tap." (As DiBergi watches Dereks performance, David and Nigel pull their bass player aside to tell him that hes "missing something in terms of thrust" in his "power zone," which prompts the zucchini solution.)
