I used to see Jeff Goldblum at Gold's Gym Venice all the time. He was/is a regular. He was Goldblumish in real life but a nice fella with good gym etiquette allowing people to work in. I shared a Smith Machine with him and was watching him making odd faces in the mirror while squatting with one 45 lb on each side. The set ended and he didn't turn into The Fly.
Anyway, ran into him enough times that I asked if he could sign something for me. I was also being Goldblum and was trying to be bizarrely mysterious about what I wanted signed. He seemed impressed with my level of Goldblum and cooperated. Next time I saw him I told him how great he was in Death Wish and presented him the DVD to sign. He upped his Goldblum on me but seemed confused and delighted. I then mentioned that I have Death Wish 2 on DVD and, since he was in Deep Cover with Larry Fishburne, he could locate him so I could have my DVD signed. Didn't happen but I hope he's still pondering the thought.
"Hmmmmmmm... Maybe. Maybe..."
