Donald Siegel (October 26, 1912 – April 20, 1991) was an influential American film director and producer.

His name appeared in the credits of his films as both Don Siegel and Donald Siegel.

Born in Chicago, he graduated from Jesus College, Cambridge in England, and found work in Warner Bros. film library, rising to become head of the Montage Department, where he directed thousands of montages, including the opening montage for Casablanca.

In 1945 two shorts he directed, Hitler Lives? and A Star in the Night, won Academy Awards, which launched his career as a feature director.

“Most of my pictures, I’m sorry to say, are about nothing. Because I’m a whore. I work for money. It’s the American way.”

He directed whatever material came his way, often transcending the limitations of budget and script to produce interesting and adept works.

He directed two episodes of The Twilight Zone, “The Self-Improvement of Salvadore Ross” and “Uncle Simon”.

He worked with Elvis Presley and Dolores del Río in Flaming Star (1960), and with Steve McQueen in Hell Is for Heroes and Lee Marvin in the influential The Killers (1964) before a series of films with Clint Eastwood that were successful both critically and commercially.

These included the policiers Coogan’s Bluff and Dirty Harry, the Budd Boetticher-scripted Western Two Mules for Sister Sara, the cynical American Civil War melodrama The Beguiled and the prison-break picture Escape from Alcatraz.

He was a considerable influence on Eastwood’s own career as a director, and Eastwood’s film Unforgiven is dedicated to Siegel and Sergio Leone.

He has a cameo role as a bartender in Eastwood’s Play Misty For Me, and, as the director of the original Invasion of the Body Snatchers, appears as a “pod” taxi driver in Philip Kaufman’s remake.

From 1948 to 1953, he was married to the actress Viveca Lindfors, with whom he had a son, Kristoffer Tabori.

He remarried Doe Avedon in 1957 and had 4 children. He died at the age of 78 from cancer in Los Angeles, survived by his 5 children. --Wikipedia
