movie producer is an old (mid 1980's to early 90's) expression to define men who took women to hotel/motels that had "in room cameras." Sometimes concealed. The object was to record their sexual exploits.
The men said they were"movie producers" and this was the only warning the women received. Some understood others did not. There was an extra fee for the tape/s. The current furor over posting of "revenge tapes" is based on the mis-use of these videos.
