Marta Becket (August 9, 1924 – January 30, 2017) born Martha Beckett, was an American actress, dancer, choreographer and painter. She performed for more than four decades at her own theater, the Amargosa Opera House in Death Valley Junction, California.Amargosa (2000), Todd Robinson's documentary about Marta Becket, won a 2003 Emmy Award for cinematographer Curt Apduhan, in addition to the film's numerous festival awards and nominations.
Becket began ballet lessons at age 14, which eventually led to performances as a ballerina. She was in the corps de ballet at Radio City Music Hall and on Broadway she appeared in Show Boat, A Tree Grows in Brooklyn and Wonderful Town. Later, she took her one-woman show across the country, performing in small theaters and school auditoriums. She married in 1962, and she was on her way with her husband to an engagement in 1967 when, due to a flat tire, she discovered a theater in Death Valley Junction and decided to stay.
The theater was part of a company town designed by architect Alexander Hamilton McCulloch and constructed in 1923–25 by the Pacific Coast Borax Company. The U-shaped complex of Mexican Colonial-style adobe buildings included company offices, a store, a dorm, a 23-room hotel, dining room, lobby and employees' headquarters. At the northeast end of the complex was a recreation hall used as a community center for dances, church services, movies, funerals and town meetings.
Becket rented the recreation hall, then known as Corkhill Hall, began repairs and changed the name to the Amargosa Opera House. In 1970, journalists from National Geographic discovered Becket doing a performance at the Amargosa Opera House without an audience. Their profile and another in Life led to an international interest in Becket and her theater. She began performing to visitors from around the world, including such notables as Ray Bradbury and Red Skelton.
