After serving in World War II, Lumet continued his work in theater before gravitating to the fledgling television industry. He directed numerous TV series before reworking the teleplay 12 Angry Men for the big screen in 1957 -- an effort that brought him the first of several Academy Award nominations.
Following that success, Lumet directed a string of critically acclaimed screen adaptations, including Tennessee Williams's The Fugitive Kind (1959) and Eugene O'Neill's Long Day's Journey into Night (1962). Lumet reached the top of his game in the 1970s with the career-defining classics Serpico, Dog Day Afternoon and Network. In 2005, he received an honorary Oscar for lifetime achievement. Lumet died April 9, 2011.
