TC Motoring Guild's "The Great Race" 

This film was made in 1972 by members of the TC Motoring Guild. It is a comedy about a fictional MG TC sports car race taking place in the Santa Monica Mountains above Malibu, California. It was shot on 16mm film and done on a whim without any re-takes. This version has music and ending "video credits", added in 2014.
This is a great look back in time at the American sports car craze and the Malibu area as it used to be.
