Background: Mel Brooks (born Melvin Kaminsky; June 28, 1926) is an American actor, writer, producer, director, comedian, and composer. He is known as a creator of broad film farces and comic parodies. Brooks began his career as a comic and a writer for the early TV variety show Your Show of Shows. He created, with Buck Henry, the hit television comedy series Get Smart, which ran from 1965 to 1970.
Context: For several years, Brooks had been toying with a bizarre and unconventional idea about a musical comedy of Adolf Hitler. Brooks explored the idea as a novel and a play before finally writing a script. Eventually, he was able to find two producers to fund the show, Joseph E. Levine and Sidney Glazier, and made his first feature film, The Producers, in 1967.  The Producers was so brazen in its satire that major studios would not touch it, nor would many exhibitors. Brooks finally found an independent distributor who released it as an art film, a specialized attraction. In 1968, Brooks received an Oscar for Best Original Screenplay for the film, beating such writers as Stanley Kubrick and John Cassavetes. The Producers became a smash underground hit, first on the nationwide college circuit, then in revivals and on home video. Brooks later turned it into a musical, which became hugely successful on Broadway, receiving an unprecedented twelve Tony awards.  With the moderate financial success of the film The Producers, Glazier financed Brooks' next film in 1970, The Twelve Chairs. Loosely based on a Russian 1928 novel The Twelve Chairs by Ilf and Petrov about greedy materialism in post-revolutionary Russia, the film stars Ron Moody, Frank Langella, and Dom DeLuise as three men individually searching for a fortune in diamonds hidden in a set of 12 antique chairs. Brooks makes a cameo appearance as an alcoholic ex-serf who "yearns for the regular beatings of yesteryear." The film was shot in Yugoslavia with a budget of $1.5 million. The film received poor reviews and was not financially successful.
