The joke that the security guard tells his partner, about the man betting a bartender he can pee in a glass, is also featured in Robert Rodriguez' earlier film Desperado (1995) in which it was delivered by Quentin Tarantino.
Robert Rodriguez had written the initial screenplay for Hypnotic back in 2002, calling it one of his favorite stories.
The first film directed by Robert Rodriguez to be primarily filmed in the anamorphic format. He previously used the format on Chapter 14: The Tragedy (2020) and The Book of Boba Fett (2021).
Originally scheduled to be filmed in Los Angeles and throughout California in 2020, all locations were scouted and sets were built at Santa Clarita Studios when the Covid shutdown halted production and did not resume until the following year in Texas.
Hypnotic was originally scheduled to be released theatrically in the United States by Solstice Studios. In March 2023, it was reported that Ketchup Entertainment would serve as the domestic distributor after Solstice Studios shut down in late-2022.
