Here is a strange one......Gary Cole on wooden bridge.....
I am not kidding - I have seen this flick probably 20 or 30 times and until tonight, I never realized that the man Petersen chases on the wooden bridge is Gary Cole.
There is a Youtube video about re-visiting the filming location scenes in this movie and the poster mentions that this was Gary Cole's debut (if I remember right, this guy is a bit pudgy, too - but I could be wrong).
I thought the Youtube video creator was wrong, but I checked at IMDb and Cole is listed as that character in an uncredited role.
