Mel Brooks

Has frequently cast himself, Gene Wilder, Harvey Korman, Rudy De Luca, Madeline Kahn, Cloris Leachman, Dom DeLuise, Ron Carey, Marty Feldman and Kenneth Mars.
Almost always uses music by John Morris
Frequently uses the line: "We have much to do and less time to do it in."
His films usually contain many Jewish references and jokes
Always features one scene in his movies in which the main character is seated and staring blankly, wondering what went wrong, while friends console him.

Best friends with Carl Reiner. Both of them widowers, they hang out and watch movies together every night.
Called his late wife, Anne Bancroft, his Obi-Wan Kenobi as she had encouraged him to turn his movie The Producers (1967) into a Broadway musical.
Brooks introduced himself to Anne Bancroft in 1961 while she was making her first appearance on Perry Como's Kraft Music Hall (1948) (she would later return to appear on that show on various occasions over several years). Brooks bribed a woman who worked on the show to tell him at which restaurant Bancroft was going to dine so he could "accidentally" bump into her again and strike up a conversation. It worked. The two fell in love and eventually married at New York City's municipal Marriage Bureau in Lower Manhattan, where a passerby served as witness.
Brooks has stated that he includes so many jokes about Hitler and the Nazis in his movies because he wants to make them both seem so ridiculous that their beliefs never became popular again. However, he added that he absolutely refuses to include any jokes about the Holocaust or other atrocities.
His parents, Kate (nee Brookman) and Aharon Mordechai "Max" Kaminsky, were Jewish emigrants. His father was born in Tilsit, then in Prussia (now Russia), with ancestors from the area which is present-day Belarus. His mother was born in Kiev, Russian Empire (now Ukraine). Brooks is an avid fan of Russian literature, occasionally making references to works and writers in his films.

Why should I indulge myself and do a David Lean-ish kind of film? I could do my little Jewish Brief Encounter (1945) and disguise it - shorten the noses. But it wouldn't be as much fun as delivering my dish of insanity.
I cut my finger. That's tragedy. A man walks into an open sewer and dies. That's comedy.
My movies rise below vulgarity.
Critics can't even make music by rubbing their back legs together.
Oh, I'm not a true genius. I'm a near genius. I would say I'm a short genius. I'd rather be tall and normal than a short genius.
