The Living Theatre is an American theatre company founded in 1947 and based in New York City. It is the oldest experimental theatre group in the United States. For most of its history it was led by its founders, actress Judith Malina and painter/poet Julian Beck. After Beck's death in 1985, company member Hanon Reznikov became co-director with Malina; the two were married in 1988. After Malina's death in 2015, her responsibilities were taken over by her son Garrick Maxwell Beck, Tom Walker and Brad Burgess. The Living Theatre and its founders were the subject of the 1983 documentary Signals Through the Flames.
