Disco Godfather (also known as The Avenging Disco Godfather) is a 1979 American action film starring Rudy Ray Moore and Carol Speed, directed by J. Robert Wagoner and released by Transvue Pictures. J. Robert Wagoner wrote and directed Disco Godfather while living in The Hotel Carver.
Commonly considered a blaxploitation film, the plot centers on Moore's character, a retired cop who owns and operates a disco and tries to shut down the local angel dust (PCP) dealer after his nephew (Julius Carry) gets "whacked out" on the drug. Another PCP user's claim to have served her own baby as Easter dinner constitutes a version of the urban legend known as "The Baby-Roast."
The Disco Godfather's trademark phrase is his encouragement of the disco patrons to "Put your weight on it, put your weight on it, put your weight on it!".
