Fool's Paradise (2023) review

A mentally-challenged, non-verbal man (Day) gets thrown out of the medical facility he was in, is immediately picked up by a producer (Ray Liotta) to replace a difficult "method actor" (also Day), acquires a hyper-active publicist (Ken Jeong), marries an actress Christiana Dior (Kate Beckinsale), stars in a dud (Mosquito Boy), ruins his career, loses his wife ... and then enters politics.  Day, in his directorial debut, is credited with writing the script - which bears a resemblance to the 1979 Hal Ashby movie Being There (which is based on the novel by Jerzy Kosiński) - but it makes the absolutely bewildering decision of using a disabled person for "humor" in an unnecessary attempt to "satirize" Hollywood: almost everyone is aware they're vacant and self-obsessed.  It couldn't buy a laugh with Ray Dalio's credit card and wastes a stellar supporting cast, which includes Edie Falco as his agent, Jason Sudeikis as a Michael Bay-type director, Jason Bateman as a technician and John Malkovich as a sinister politician.  Any individual episode of It's Always Sunny in Philadelphia is more entertaining ... maybe he needed The Gang to help him fix this.
