Visible crew/equipment: In the scene where Captain Stotlemeyer is putting one of the large snakes back in the glass container, he turns and the base of his wireless microphone is visible when his jacket gets bunched up.

Factual error: When Stottlemeyer backs up the video tape at Monk's house, we can hear the sound chattering backwards. Only a huge industrial (studio) machine would do that. Little home VCRs, like Monk's, mute the sound during in-play rewind and fast forward modes.

Continuity: In the cemetery scene, Stottlemeyer approaches the grave of the 17 year old open case hit and run victim. The dates on his grave are 1980-1997. But in Dennis Gammill's confession letter in the end, it says he killed the boy in December 1998.
