I did not see this 1975 Movie starring the then young Don Johnson and Nick Nolte. Return to Macon County stars a beautiful 1957 Chevrolet in a movie very similar to 2 Lane Blacktop. I do not have any good pictures of this movie to provide, although I do have the movie.

looks like it would be a good movie for image captures. i've all to see if i can find it on DVD. thanks for the mention of the 57 Chevy.

btw..is it used during the whole movie and is it a coupe or a sedan? i choose coupe since the art for the movie poster looks like a coupe.

It is used for the whole movie. It is a feature car much like the '55 Chevy of "Two-Lane Blacktop." I believe you are right in that it is a coupe, but I would have to watch it again to be positive.
