Two Lane Blacktop
This 1971 film pairs a young James Taylor (yep, the musician) and Dennis Wilson (the drummer for The Beach Boys) as a drag
racing duo. The two of them set off across the U.S. racing a gray 1955 Chevy. Along the way the meet up with a girl played by Laurie Bird and a classic jealous love triangle ensues. Also, they meet an odd, possibly crazy, man in a Pontiac GTO, who makes things even more interesting.
