During the filming of an intimate scene in Sweet Sweetback's Baadasssss Song -- and yes, I copied and pasted it to ensure the correct number of a's and s's-- Marvin Van Peebles contracted gonorrhea from one of his co-stars. What can I say, the man did his own stunts.
Anyway, due to the unforeseen malady, Mr. Van Peebles applied to the director's guild for worker's comp, and was successful. He used the money to purchase more film. What a trooper.
