Born into a family of actors, Sidney Lumet was a well-known child player on the stage (and in one film), but had dropped out of acting by the end of World War II. He got into television in its earliest days, and, after a short time as an assistant director (to Yul Brynner, amongst others), became phenomenally busy in live drama. He was, by the mid-1950s, amongst the most renowned television directors in the world, and he made quite a splash with his first movie, "Twelve Angry Men". He directed several plays on Broadway, too (using TV directors in the theatre was a fashion of the 50s), but,
… More with the advent of the 60s, he was concentrating on cinema. He was prolific in this medium for forty years, but returned to television at the dawn of the twenty-first century. Famous for his avoidance of Hollywood (it was not until 1986 that he made his first and only film there), he has been married four times and is the author of a book called "Making Movies".
