Today marks the birthday of legendary B-movie producer and distributor Samuel Z. Arkoff, who is responsible for such master strokes of skinema as Coffy (1973), Thriller: A Cruel Picture, and (1974) Prison Girls (1972). Arkoff attributed his success to his insistence that all his movies should adhere to a formula, which he revealed during an interview in the 1980s.

1. Action

2. Revolutionary Ideas

3. Killing or Violence

4. Notable Dialogue

5. Fantasy

6. Fornication

While I would never presume to question the master's wisdom, I have to admit that, even if it leaves out the first five, I'll watch any movie that has number six. Or at least fast forward to the good parts.
