Play it as it lays (1972)

Burned-out B-movie actress Maria, depressed and frustrated with her loveless marriage to an ambitious film director, Carter Lang, who would rather work on his career than on his relationship with her, numbs herself with drugs and sex with strangers. Only her friendship with a sensitive gay movie producer, B.Z., offers a semblance of solace. But even that relationship proves to be fleeting amidst the empty decadence of Hollywood.
