I saw The Producers, as well... What I have to say about it: Eeeeeeh... It was ok by my standards. There was something about it that made it sort of... distant? Maybe it was the fact that it was literally the show on screen. All of those jokes... the songs... the little gags.. they're made more for the stage than the screen.
But it was fun to catch all the little references they made to other Mel Brooks films!!!! Well... I only really caught one reference... I don't think there were any others. ^^
"And I said, Not in MY backyard, utensils! Go back to {China}!"... bidi BAH...
