Martin Landau, an Oscar winner for his supporting role in Tim Burton's "Ed Wood" (1994), has died at 89, THR reports.
In a statement, his rep confirmed Landau died unexpectedly Saturday.
The statement read, "We are overcome with sadness to report the death of iconic actor Martin Landau on July 15, 2017, at 1:30 p.m. at UCLA Medical Center, where he succumbed to unexpected complications during a short hospitalization. He had just celebrated his 89th birthday."
Landau had been described as a "guiding force" in the Actors Studio for over 60 years, and was serving as Artistic Director of Actors Studio West at the time of his death.
A familiar face on TV, Landau played Rollin Hand on the hit series "Mission: Impossible" from 1966-1969, winning a Golden Globe Award and receiving Emmy nominations each season. He left the show, which also starred his then wife Barbara Bain, in a contract dispute.
He played Commander John Koenig (again opposite Bain) on the cult hit "Space: 1999," a British series, from 1975-1977. He received another three Emmy nominations, for his work on "Without a Trace" in 2004 and 2005, and for "Entourage" in 2007.
Landau's film debut was in 1959's "Pork Chop Hill" starring Gregory Peck, but his first big splash, that same year, was as a menacing henchman in the Alfred Hitchcock classic "North by Northwest," starring Cary Grant and Eva Marie Saint.
Other early film highlights include appearances in the epics "Cleopatra" (1963) with Elizabeth Taylor and Richard Burton, and "The Greatest Story Ever Told" (1965).
Landau's film career was reignited by his Oscar-nominated performance in "Tucker: The Man and His Dream" (1988). The following year, he turned in a second Oscar-nominated performance, in Woody Allen's "Crimes and Misdemeanors" (1989). Landau won the Oscar and a slew of other prestigious awards for "Ed Wood," in which he played legendary horror actor Bela Lugosi.
Since then, Landau had worked steadily in film, including starring opposite Paul Sorvino in "The Last Poker Game," which premiered at the 2017 Tribeca Film Festival in New York.
Landau was a regular fixture at autograph conventions, and was happy to appear at events to speak about his work.
He is survived by his two daughters, a granddaughter and one sister. The statement provided by his rep also noted he is survived by ex-wife Bain, to whom he was married from 1957-1993.
