Is this the movie...
... Where someone is standing on the street and sees a crosswalk sign that is flashing "DONT WALK" and he looks back at it and it has changed to "RUN"?
I saw a movie probably in the early 1970s with this scene in it, and was wondering if this is the same one. I don't remember who was in that one, but it was pretty creepy.
Would love to see it again.
