My cousin is good friends and still in contact with Cathy Moriarty who came to a Christmas dinner at my aunt house. I remember her siting on the couch as my nephew trying to pick her up. She was sixteen and he was 10. It was cute.
My understanding is that she was modeling and was spotted and got the role of Vicki LaMotta in Raging Bull with Bobby Deniro. My cousin is supposedly in that film in the pool scene. She was in the next chair next to Cathy. I have seen the film but didn't recognize her as she was wearing a brown wig and I am used to seeing her as a blond.
My son has met several celebrities as he worked in many top hotels they frequent. Like Shaquille O'Neal and Dan Marino. He's talked to Madonna, Stephen King, and others he probably hasn't mentioned.
