The shot of the police cadets jogging under the "Santa Regina Police Academy" sign was filmed at the same location as the Los Angeles Police Academy scene in the Charlie's Angels TV series (used in the show opening). In that series, in which the shot was filmed at the same angle, the sign just says "Police Academy" on it.
When Jamie's at the police academy, undergoing training, she's in a car chase at a movie studio backlot. During this chase, they pass by what is unmistakeably Jim Rockford's trailer from The Rockford Files (1974). Additionally, Lindsay Wagner guest starred in Backlash of the Hunter (1974) and Aura Lee, Farewell (1975), playing the same character.
