At the end of the film, when the detective drives to Morningside High School, the Century Drive-In Theater is seen across the street at 3560 W. Century Blvd. In 1963, the huge Cinerama screen was installed there. In 1984 it was closed, and turned into a shopping center.
The car Lt. Williams drives is a 1959 Chevrolet Biscayne with whip antennae, probably an Inglewood Police unmarked car. The car Ralph drives is a 1960 Ford Fairlane. The car the man who takes Mike drives is a 1959 Ford Thunderbird.
