In the third season of the sopranos there is a scene where Tony is talking to another mob guy at a restaurant. If you look closely, you will see William DeMeo in the background changing a light bulb. His acting was very authentic in that scene, you actually believe he was changing an actual light bulb.
He was in another mob movie about the Polish mafia where he was also changing a light bulb except there were 3 guys changing the light bulb. Some cool stuff.
