13 Moons is a 2002 comedy-drama film directed by Alexandre Rockwell. The title is a reference to the saying of a minor character's mother, who suggested that if nights of the full moon are strange, then "this must be the night of thirteen moons."^[1][2]

Bananas The Clown is run over by his wife Suzi who has discovered his stripper girlfriend Louise. When his wife is jailed for trying to run him over, they contact a bail bondsman. The bondsman is busy taking care of his sick son Timmy. On the way, they are accosted by a crazed drug addict named Slovo who is hit by a car soon after.

At the jail, the five meet up with an angry record producer and the girlfriend he believes to be pregnant whom he plans to make a star, despite her protestations of not having any talent. Also along for the ride are two priests, one of whom has begun to doubt the wisdom of the Roman Catholic Church, and who are trailing to bail out a third priest who was goaded into a fight by the proprietor of a strip club.

When the nine characters intersect, they discover that Timmy has a defective kidney and is slowly dying. He has just been paged, as there is a donor at the hospital: Slovo. The three caring characters immediately take Timmy to the hospital, with the others in pursuit. By the time they arrive, Slovo partially recovered and escapes to wander the streets, cheerfully ignoring his internal bleeding and must be tracked down, before both he and Timmy die.

In 2023 review of the film, The Herald stated "“13 Moons,” from 2002, is not a good film, but it has a key insight that’s exceedingly rare in the filmmaking world. See, most bad movies end up that way because they tried to be good and failed. If being good was never the intention, though, strange new opportunities present themselves."^[3]
