Child actor Mineo's mother enrolled him in dancing and acting school at an early age. He had his first stage appearance in
Tennessee Williams's play
The Rose Tattoo (1951). He also played the young prince opposite
Yul Brynner in the stage
musical The King and I. Brynner took the opportunity to help Mineo better himself as an actor. On May 8, 1954, Mineo portrayed the Page (lip-synching to the voice of
mezzo-soprano Carol Jones) in the
NBC Opera Theatre's production of
Richard Strauss's
Salome (in English translation), set to
Oscar Wilde's
play.
Elaine Malbin performed the title role, and
Peter Herman Adler conducted
Kirk Browning's production. As a teenager, Mineo appeared on
ABC's musical quiz program
Jukebox Jury. Mineo made several television appearances before making his screen debut in the
Joseph Pevney film
Six Bridges to Cross (1955). He beat out
Clint Eastwood for the role. Mineo successfully auditioned for a part in
The Private War of Major Benson (1955), as a cadet colonel opposite
Charlton Heston.
Rebel Without a Cause and stardom in a publicity still photo for
Rock, Pretty Baby (1956) Mineo's breakthrough as an actor came in
Rebel Without a Cause (1955), in which he played John "Plato" Crawford, a sensitive teenager smitten with main character Jim Stark (played by
James Dean). In
Giant (1956), Mineo played Angel Obregon II, a Mexican boy killed in World War II. Many of his subsequent roles were variations of his role in
Rebel Without a Cause, and he was typecast as a troubled teen. In the
Disney adventure
Tonka (1958), for instance, Mineo starred as a young
Sioux named White Bull who traps and domesticates a clear-eyed, spirited wild horse named Tonka that becomes the famous
Comanche, the lone survivor of
Custer's Last Stand. By the late 1950s, Mineo was a major celebrity. He was sometimes referred to as the "Switchblade Kid", a nickname he earned from his role as a criminal in the movie
Crime in the Streets (1956). The more popular of the two, "
Start Movin' (In My Direction)", reached No. 9 on
Billboards pop chart. It sold over one million copies and was awarded a
gold disc. He starred as drummer
Gene Krupa in the movie
The Gene Krupa Story (1959), directed by Don Weis with
Susan Kohner,
James Darren, and
Susan Oliver. He appeared as the celebrity guest challenger on the June 30, 1957, episode of ''
What's My Line?'' Mineo made an effort to break his
typecasting. In addition to his roles as an Indian brave in
Tonka (1958), he played a Jewish Holocaust survivor in
Exodus (1960); for his work in
Exodus, he won a
Golden Globe Award and received his second Academy Award nomination for
Best Supporting Actor. Mineo was the model for
Harold Stevenson's painting
The New Adam (1963). Now in the Guggenheim Museum's permanent collection, the painting is considered "one of the great American
nudes". Mineo also appeared on the Season 2 episode of
The Patty Duke Show: "Patty Meets a Celebrity" (1964). Mineo's role as a
stalker in
Who Killed Teddy Bear (1965), which co-starred
Juliet Prowse, did not seem to help his career. Although his performance was praised by critics, he found himself typecast again—this time as a deranged criminal. The high point of this period was his portrayal of Uriah in
The Greatest Story Ever Told (1965). Mineo guest-starred in an episode of the TV series
Combat! in 1966, playing the role of a GI wanted for murder. He did two more appearances on the same show, including appearing in an installment with
Fernando Lamas. In 1969, Mineo directed a Los Angeles production of the gay-themed play ''
Fortune and Men's Eyes'' (1967), featuring then-unknown
Don Johnson as Smitty and Mineo as Rocky. The production received positive reviews, although its expanded
prison rape scene was criticized as excessive and
gratuitous. Mineo's last role in a motion picture was a small part in the film
Escape from the Planet of the Apes (1971); he played the chimpanzee
Dr. Milo. In December 1972, Mineo stage-directed the
Gian Carlo Menotti short opera
The Medium in Detroit.
Muriel Costa-Greenspon portrayed the title character, Madame Flora, and Mineo played the
mute, Toby. In 1975, Mineo appeared as Rachman Habib, the assistant to a murderous consular head (portrayed by
Hector Elizondo) of a Middle Eastern country, in the
Columbo episode "
A Case of Immunity," on
NBC-TV. One of his last roles was a guest spot on the TV series
S.W.A.T. (1975), in which he portrayed a cult leader similar to
Charles Manson. By 1976, Mineo's career had begun to turn around. While playing the role of a
bisexual burglar in a series of stage performances of the comedy
P.S. Your Cat Is Dead in San Francisco, Mineo received substantial publicity from many positive reviews; he moved to Los Angeles along with the play. ==Personal life==
