The Man with Bogart's Face (also called Sam Marlowe, Private Eye) is a 1980 American comedy film, released by 20th Century Fox and based on a novel of the same title.
A man calling himself Sam Marlowe (Robert Sacchi) has his face altered to resemble that of his idol, Humphrey Bogart, and then opens a detective agency.
At first, he and his secretary Duchess (Misty Rowe) have meager business, but things pick up after a shooting puts Sam's picture in the paper.
Some ruthless people, who are coincidentally also similar to characters in Bogart films (and played by Victor Buono, Herbert Lom, and Michelle Phillips), are after a priceless set of blue sapphires called the Eyes of Alexander (from a statue of Alexander the Great), and Marlowe and Duchess are caught in the middle of it all.

[1] The New York Times called it "an intelligent, amiable and often amusing spoof of Humphrey Bogart and the roles he played" although "everyone is so cool that there are moments when the picture seems about to drift off the screen".
