As Chapter 3 begins, Webb and Towne are driving the same 1941 Ford convertible we first saw in Chapter 1, but as the chase ensues, they are now driving a 1940 Ford convertible, which has a much different radiator and headlight assembly.
In the freshly filmed sequences, the police drive 1950 Nash sedans, but in the frequently seen stock footage, they revert back to 1936 Fords.
Although 'Charles Regan' is listed in screen and press cast, he did not appear in this film.
