The comedy movie is probably 15-30 years old. I only saw the first half of the movie a few years ago and forgot the actor(s) or actresses. PLOT- The screenwriter or producer could not get financial support to produce/direct his film so he came up with a scheme to create/film scenes at random locations with unsuspecting actors/actresses that he wanted to include in the plot of his film. He would have someone approached them with scripted questions as he was filming from a distance. For instance, he would catch them coming out of a restaurant, etc
Thanks for any help.
