Instant Theatre
Shortly after her arrival in Los Angeles in 1955, the French-born dancer and performer Rachel Rosenthal began to run improvisation workshops that attracted both inexperienced and seasoned actors. When she enthusiastically suggested that the group perform for an audience, however, all but a handful left. Undeterred, she founded Instant Theatre with those who remained. Over the next decade, Instant Theatre’s cast and home were constantly in flux. In 1963, for instance, the group performed at this location, which at the time was named the Horseshoe Stage Theater.
