Martin Landau, the chameleon-like actor who gained fame as the crafty master of disguise in the 1960s TV show "Mission: Impossible," then capped a long and versatile career with an Oscar for his poignant portrayal of aging horror movie star Bela Lugosi in 1994's "Ed Wood," has died. He was 89.

Landau died Saturday of unexpected complications during a short stay at UCLA Medical Center, his publicist Dick Guttman said.

"Mission: Impossible," which also starred Landau's wife, Barbara Bain, became an immediate hit upon its debut in 1966. It remained on the air until 1973, but Landau and Bain left at the end of the show's third season amid a financial dispute with the producers. They starred in the British-made sci-fi series "Space: 1999" from 1975 to 1977.

Landau might have been a superstar but for a role he didn't play — the pointy-eared starship Enterprise science officer, Mr. Spock. "Star Trek" creator Gene Rodenberry had offered him the half-Vulcan, half-human who attempts to rid his life of all emotion. Landau turned it down.

Instead, he chose "Mission: Impossible," and Leonard Nimoy went on to everlasting fame as Spock. Ironically, Nimoy replaced Landau on "Mission: Impossible."

After a brief but impressive Broadway career, Landau had made an auspicious film debut in the late 1950s, playing a soldier in "Pork Chop Hill" and a villain in the Alfred Hitchcock classic "North By Northwest."

He enjoyed far less success after "Mission: Impossible," however, finding he had been typecast as Rollin Hand, the top-secret mission team's disguise wizard. His film career languished for more than a decade, reaching its nadir with his appearance in the 1981 TV movie "The Harlem Globetrotters on Gilligan's Island."

He began to find redemption with a sympathetic role in "Tucker: The Man and his Dream," the 1988 Francis Ford Coppola film that garnered Landau his first Oscar nomination.

He was nominated again the next year for his turn as the adulterous husband in Woody Allen's "Crimes and Misdemeanors."

His third nomination was for "Ed Wood," director Tim Burton's affectionate tribute to a man widely viewed as the worst Hollywood filmmaker of all time.

In "Ed Wood," he portrayed Lugosi during his final years, when the Hungarian-born actor who had become famous as Count Dracula was ill, addicted to drugs and forced to make films with Ed Wood just to pay his bills.

Landau studied drawing at the Pratt Institute in Brooklyn and worked for a time as a New York Daily News cartoonist before switching careers at age 22.

He had dabbled in acting before the switch, making his stage debut in 1951 at a Maine summer theater in "Detective Story" and off-Broadway in "First Love."

In 1955, he was among hundreds who applied to study at the prestigious Actors Studio and one of only two selected. The other was Steve McQueen.

Landau and Bain had two daughters, Susan and Juliet. They divorced in 1993.
