Herbert Ross, on a roll that continued through the 1970s, became that rare director of a Woody Allen screenplay who wasn’t (also) the star himself; Allen adapted his own Broadway play with he, Diane Keaton, Tony Roberts, and Jerry Lacy all re-creating their stage performances for the screen version. Lacy successfully incarnates Casablanca-era Humphrey Bogart as spirit avatar to Allen’s film writer/movie buff, materializing for advice and/or bull sessions as the latter attempts to navigate post-marital single life in — unusually, for Allen — San Francisco.
