The producers, 1968 Mel Brooks movie. DVD used.

A "startling, stunning, outrageous, breathtaking debut" (Los Angeles Times) from acclaimed writer/director Mel Brooks (Young Frankenstein, Spaceballs), this Oscar-winning* comedy combines "pure pell-Mel lunacy [and] wild, ad-lib energy [into an] uproariously funny"  film! Low-rent Broadway producer Max Bialystock (Zero Mostel) and his high-strung accountant, Leo Bloom (Gene Wilder), discover that, with the help of a few gullible investors, they can make more money on a flop than on a hit! Armed with the worst show ever written ("Springtime for Hitler") and an equally horrific cast, this double-dealing duo is banking on disaster. But when their sure-to-offend musical becomes a surprise smash hit, they find themselves in the middle of a Broadway blitzkrieg! *1968: Original Screenplay
