Trivia: This show pays many homages to the 1968 film Bullitt which was also set in San Francisco. Firstly officer Rebecca Madsen's car is the exact same make, colour, and model Mustang that Steve McQueen drove in Bullitt. Also the final episode (Tommy Madsen) features a car chase which recreates many shots from the 1968 film. It even includes the green Beetle Volkswagen coming down the hill as seen in the movie.
