Interesting uncredited role....
I'm surprised to discover that the young woman about to use the public telephone but rushed in instead by the Fly is actress Brooke Adams in an uncredited role. Brooke Adams would star 2 years later in the equally superb version of Invasion Of The Body Snatchers. I thought that anyone, though I don't know what constitutes the criteria, in the camera would deserve credit for appearing. I thought this was the case with then unknown actress Sigourney Weaver in Woody Allen's Annie Hall. She appears on screen for 13(?) seconds or less in the background.
Anyway, Car Wash is hilarious. Big ups.
What you see is not necessarily what you get,
Not trying is dying, keep trying unto death....
