Walter Jack Palance ( PAL-əns; born Volodymyr Ivanovich Palahniuk; February 18, 1919 – November 10, 2006) was an American screen and stage actor, known to film audiences for playing tough guys and villains. He was nominated for three Academy Awards, all for Best Actor in a Supporting Role, for his roles in Sudden Fear (1952) and Shane (1953), and winning almost 40 years later for City Slickers (1991).

Born in Lattimer Mines, Pennsylvania, the son of Ukrainian immigrants, Palance served in the United States Army Air Forces during World War II. He attended Stanford University before pursuing a career in the theatre, winning a Theatre World Award in 1951. He made his film acting debut in Elia Kazan's Panic in the Streets (1950), and earned Oscar nominations for Sudden Fear and Shane, his third and fourth-ever film roles. He also won an Emmy Award for a 1957 teleplay Requiem for a Heavyweight.

Subsequently, Palance played a variety of both supporting and leading film roles, often appearing in crime dramas and Westerns. Beginning in the late 1950s, he would work extensively in Europe, notably in a memorable turn as a charismatic-but-corrupting Hollywood mogul in Jean-Luc Godard's 1963 film Contempt. He played the title character in the 1973 television film Bram Stoker's Dracula, which influenced future depictions of the character. During the 1980s, he became familiar to a new generation of audiences by hosting the television series Ripley's Believe It or Not! (1982–86). His newfound popularity spurred a late-career revival, and he played high-profile villain roles in the blockbusters Young Guns (1988) and Tango & Cash (1989), and culminating in his Oscar and Golden Globe-winning turn as Curly in City Slickers.

Off-screen, he was involved in efforts in support of the Ukrainian American community and served as a chairman of the Hollywood Trident Foundation. He continued to act in films until his death from natural causes in 2006, at the age of 87.
