Aiden Quinn while they were shooting Elementary. Almost ran into him.
John & Bo Derek at Rockefeller center
Helen Mirren twice , once by Tourneau Corner on 57th and once downtown NY while they were shooting. Her "handler" moved between us when I said "Hey that's Helen Mirren" my buddy said, "Who"
Soupy Sales on 3rd Ave. We were in a deli getting lunch.
Minnie Driver in Battery park. I think she was promoing her album at J&R music store (which is gone now).
I spotted Brook Shields, Meg Ryan and I think Mayim Bialick.
Oh yea. They film the TV show Power on my block about 3-4 times a year for the last 3 years. I don't know the show or who is in it. I did take pictures of the cars they used.
