[4] The film stars Nicolas Cage, who also served as producer, along with Emily Tosta, Ric Reitz, David Sheftell and Beth Grant.

It follows a quiet drifter who is tricked into cleaning up an abandoned family entertainment center inhabited with eight murderous animatronic mascots who are possessed with the souls of a cannibalistic killer and his colleagues.

When his vehicle breaks down outside Hayesville, Nevada, a quiet drifter is picked up by local mechanic Jed Love, who takes him to Willy's Wonderland, a once-successful abandoned family entertainment center inhabited with eight now-withered animatronic mascots: Willy Weasel, Arty Alligator, Cammy Chameleon, Ozzie Ostrich, Tito Turtle, Knighty Knight, Gus Gorilla, and Siren Sara.

The restaurant's owner Tex Macadoo offers him to work as a night-shift janitor in exchange for repairing his vehicle before he and Jed leave him locked inside it.

In the ensuing chaos, Knighty fatally impales Aaron with his sword, Dan is eaten alive by Tito and Sara, and Arty mauls Kathy and Bob to death in a party room.

Over the years, they tricked random drifters into cleaning up the restaurant, offering them as human sacrifices in order to stop the animatronics' killing spree.

Also appearing in supporting roles are Jason Tyler as Eric Miller, a construction worker hired to demolish the restaurant; Ryan Kightlinger as a biker hired as a previous janitor; Joseph and Jessica Teagle as a Hippie couple also hired as previous janitors; Lawreen K. Yakkel, Ashann Bachan, Kevin Brown, Eduardo Lozano, Nathaniel Smith Jr., and D. J. Stavropoulos as members of Jerry Robert Willis' satanic cult; Michael Woodruff, J. J. Madaris, Robert Howell, Chris Speck, Benton Eden, and Elliott Boswell as ATF agents; Jared Soto as a homeless man; Kandace Lee as a smoker killed by Willy Weasel, and Miles Woodruff as a birthday boy from the flashbacks.

[6] Kevin Lewis was hired as director while the cast, including Emily Tosta, Beth Grant and Ric Reitz, joined in February 2020.

[10] After the announcement, the film received a small cult following, with many comparing it to the Five Nights at Freddy's video game series, although Parsons and Lewis denied any similarities.

[11] Certain changes were made during production; the title was changed from Wally's Wonderland to Willy's Wonderland due to legal issues; and original animatronic characters Douglas Dog, Pauly Penguin, Beary Bear, Pirate Pete, and Regina Rabbit were replaced with Arty Alligator, Tito Turtle, Gus Gorilla, Knighty Knight, and Cammy Chameleon, respectively.

Lewis described the film as "Pale Rider vs. Killer Klowns from Outer Space", and cites Panos Cosmatos' Beyond the Black Rainbow as an inspiration.

[18] Willy's Wonderland was scheduled for worldwide theatrical release on October 30, 2020, but was removed from the calendar due to the COVID-19 pandemic causing the closure of theaters across the globe.

The site's critical consensus reads: "Willy's Wonderland isn't quite as much fun as its premise would suggest—but it's still got Nicolas Cage beating the hell out of bloodthirsty animatronics, which is nice.

[23] Nick De Semlyn of Empire gave the film a score of three out of five stars, concluding that, "though the dialogue and plotting are no great shakes, that commitment to the concept, combined with Cage's swaggering soda-swigger, is enough to make this a good time.

"[24] IGN's Matt Fowler rated the film six out of ten, writing that "There's not enough here to score high marks, but there's cartoonish carnage aplenty and that warrants a passing grade.

"[25] Anton Bitel from VODzilla.com awarded the film a score of seven out of ten, saying: "It is set in an amusement centre for children, but comes with adult doses of foul-mouthed language, sex, gore and death.

[27] Alix Turner of Ready Steady Cut wrote: "Daft plot, fabulous fight scenes, teenagers in peril and plenty of gore.

[29] Nicolás Delgadillo of DiscussingFilm.net called the film "unapologetically ridiculous" and "a bizarre hidden gem thrown into Cage's already vast and eclectic body of work.
