database for cars used in movies??

[corporalcripp]

I can't be the only one who wonders but.....I'll be watching a movie & notice the car an actor is driving and go,"What make is that ride?"
TCM had Hitchcock's The Birds on last nite so....Tippy Hedren(yum,yum) has this cool sports car.Maybe Alfa Romeo?I can't find any identifying badges on it.
Another is Street With No Name.Richard Widmark's "gangsta" ride looks like a Mercury or Lincoln coupe with rear fender skirts.Really cool.Looks 40s but pre or post war?Anybody know?
