It's a crazed grabbag of a movie that does everything to keep us laughing except hit us over the head with a rubber chicken. Mostly, it succeeds. It's an audience picture; it doesn't have a lot of classy polish and its structure is a total mess. But of course! What does that matter while Alex Karris is knocking a horse cold with a right cross to the jaw?

Much of the laughter Mr. Brooks inspires is hopeful, before-the-gag laughter, which can be terribly tiring...Blazing Saddles has no dominant personality, and it looks as if it includes every gag thought up in every story conference. Whether good, bad, or mild, nothing was thrown out.

No comic trope, however musty or studded with whiskers, is off limits, including bad puns, physical shtick, pie fights, goofy names and accents, song-and-dance numbers, Jewish Indians, or just having a bunch of cowpokes farting around the campfire. Some of the jokes drop like lead, but the film's anarchic spirit carries a lot of excitement, because Brooks' anything-goes philosophy means that no comedic possibilities go unconsidered.
