I don't know if this counts. I was once in a police training film. About 20 or 25 years ago I had been an actor in several local community theatre productions, all strictly amateur stuff. The film was my only paying gig. I got $25 for an afternoon's work. I can't remember how I got the job. Somebody who knew me must have recommended me. I know I didn't audition. I wasn't even looking for work. I had to take a day off from my regular job to do it, so it was a net loss. It was worth it for the experience.

I appeared in only one scene, but I actually had some speaking lines. I played a "witness" being questioned by a police officer. I hadn't witnessed an actual crime, but had seen a "suspicious" person leaving my apartment building after a rape had been committed there. When I saw the final edited version of the film, it turned out that only a couple of my lines were audible at the beginning of the scene. After that, my dialogue was just background while a "voice-over" explained proper police procedure.

They used real police officers to play the roles of policemen. Everyone else was an actor—but, like me, an amateur or nearly so, with no particular knowledge of police procedure or crime. I'm rather sure, though, that the script was written by someone who had done considerable research. I think the film (which was one of a series) was an early attempt to raise the consciousness of police officers (who were almost always male in those days) about rape, to dispel some of the sexist myths and prejudices that were then common, and to get policemen to treat rape victims with some sensitivity and respect. But I'm also rather sure that whatever procedure was considered advanced in those days has now been superseded, so my film has probably gone to landfills by now.

I don't even remember the name of the film, or the name of the production company.
