There's a 1998/99 indie movie entitled "Edge of Seventeen" that takes place in Sandusky, OH circa 1984, and at least two of the characters in the movie work in "a fast foor restaurant at a local amusement park" which is not specifically named to be CP--but what else could it be? Not having seen the movie myself, I don't know if anything was actually shot onsite or if there's any footage of any kind of the park at all (i.e. the park in the background from downtown, or shots of the park from the beach). Since CP is not explicitly mentioned (either by choice of the writers or by mandate of Cedar Fair given the theme of movie), I would guess that there is no internal park footage.
