Having watched the "Friday Western" every week as a child, I’m pretty familiar with the genre and appreciate this film's humorous and affectionate take on it. Harvey Korman plays "Hedley Lamarr," who intends to ruin his own town so he can purchase the land at reduced prices for his railroad venture. To force the residents out, he appoints an African-American sheriff. “Bart,” portrayed by Cleavon Little, is aware that he lacks any real backing from the people in his community – they’re not exactly quick on the uptake – and recruits the notorious "Waco Kid" (Gene Wilder) as his deputy. This gunslinger, along with his new boss, slowly persuade the timid townsfolk to believe they can stand up to Lamarr's scheme and possibly even thwart it. The imitation of Marlene Dietrich by Madeline Kahn singing “I’m Tired” is my favorite moment, but there are many other comedic sequences referencing films like "High Noon" and "Chisum," with Slim Pickens and David Huddleston lending some authentic western experience to the film. Director Mel Brooks makes a few appearances in various roles, adding extra humor to his already somewhat absurd plot, which acknowledges cowboy movies while also sharply commenting on their stereotypical characters, repetitive narratives, and typically predictable endings. The movie combines all of this with Little and Wilder’s excellent chemistry, delivering a genuinely funny, occasionally slapstick, commentary on a century's worth of cinema that hasn’t really changed much since 1874.
