I also managed to find the Al Pacino movie where this car was featured --- in seconds.
Amazing thing, this Google.
Here is what one reviewer wrote :
“I gave this film 3 stars for the calm, romantic, almost "haunting style" the film projects onto the viewer....and Pacino's 1976 Alfa Romeo GTV sports car, driving around those old streets of Italy rated 2 stars all by itself!”
That’s what I remember from the movie, as well; although, I think the reviewer was being a little bit too generous : I would give the car 3 stars and the movie none, to be honest!
