In the movie, Gunn mentions that there was only one black senator. This is in reference to Edward Brooke, Republican Senator from Massachusetts, who served from January 3, 1967 - January 3, 1979. At the time the film was released, Brooke was only the third African-American Senator to serve in the U.S. Congress. He was the first one to be elected and serve since 1881.
Jim Brown said during the filming of this movie he began a love affair with Brenda Sykes. "I knew they were casting for an actress to play my lover. I persuaded them to hire Brenda Sykes. Brenda had dark skin, a small waist, luminous big brown eyes . . . For five years I tried to make her mine, for five years Brenda ignored my advances. At my urging they hired Brenda. When it was time to film our love scene, it called for us both to be naked. I was protective of her, tried to calm her nerves, and Brenda began to see that I cared about her. We removed our clothes, slid into bed, did our scene. By the time we got out of the bed Brenda was my woman. Though we didn't make love, all the fires were burning. But I didn't kid myself for a second: I used the movie industry to catch Brenda. Otherwise she never would have been with me," Brown said.
Gunn's car is a white 1962 Rolls-Royce Silver Cloud III. While out looking for clues, and stopping at the B.A.G. office, the mafia bad guys are riding in a black 1965 Cadillac Fleetwood 75.

This is the movie that ignited Quentin Tarantino's drive to be a film-maker: he attended a double-feature (with The Bus Is Coming) at the Tower Theatre in 1972, and since that showing has been trying to replicate "the experience of watching a brand-new Jim Brown film, on a Saturday night, in a black cinema in 1972."
