Silva worked on Lynch’s Twin Peaks. According to David Lynch on the 2007 Gold Edition DVD release of Twin Peaks, Lynch was upstairs in the Laura Palmer house, near Silva as he worked, and suddenly realized that Silva might have a place in the show. He asked Silva if he was an actor, and Silva said that he was. Later, Lynch accidentally caught him on camera when his reflection appeared in a mirror, and thus was born the character of Killer BOB, a dark spirit who haunts Laura. Silva appeared occasionally as BOB for the remainder of the Twin Peaks series and in the 1992 movie Twin Peaks: Fire Walk with Me. His first major appearance was in the International Version of the Twin Peaks pilot, which contained a standalone ending that resolved the mystery of the series and incorporated the accidental footage.
