Where's Poppa? is a 1970 American black comedy film based on the 1970 novel by Robert Klane and starring George Segal, Ruth Gordon, Ron Leibman, and Trish Van Devere.^[2] The plot revolves around the troubled relationship between a lawyer (Segal) and his senile mother (Gordon), who keeps interfering with his love life. The film was directed by Carl Reiner, whose son Rob Reiner had a role in an early performance. Others in the cast include Paul Sorvino (in his film debut), Rae Allen, Vincent Gardenia and Garrett Morris. The film was re-released in 1975, under the title Going Ape, and maintains a cult following.^[3]

Gordon Hocheiser has had some success as a lawyer working as a criminal defense attorney in New York City. However, he still cares for and lives with his mother, a rude, possibly senile 87-year-old widow, who is ruining her son's love life. He resents her so much that he tries to scare her to death by donning a gorilla suit and attacking her in bed, only to end up being hit hard in the groin by her. Nevertheless, she seems unaware of his intentions and refers to him as a "good boy." Despite his deep resentment for his mother and his desire to be rid of her, Gordon had made a deathbed promise to his father not to place her in a rest home, which causes him severe anguish. She continuously asks, "Where's Poppa?" His repeated response is, "Still dead."

He is desperate to hire a nurse for help but, since his mother has already had conflicts with many of them, no one will agree take the job. Gordon finally locates Louise, a young and beautiful nurse whose patients have a peculiar habit of dying in her care. Instantly smitten with her, he hires Louise to be his mother's companion, despite her notable lack of any qualifications. Thrilled about his budding love, he immediately becomes frightened that his mother will sabotage it and, when he invites Louise over to his apartment on the Upper West Side, he tries to lock his mother away in her room.

After a disastrous first meeting between Louise and his mother, a frustrated Gordon calls his brother Sidney and threatens to kill his mother if he doesn't immediately take her off his hands. Worried that Gordon will actually carry through with his threats, Sidney, who lives with his family on the Upper East Side, ignores the protests of his wife and runs in the middle of the night across Central Park, where he has a history of repeatedly being mugged. As expected, his muggers again confront him and steal his clothes.

When a naked Sidney arrives at Gordon's apartment, Louise has already left so, after agreeing to help the next time he needs him, Sidney borrows the gorilla costume and wears it home. Soon after, Louise returns and, realizing that this may be his last chance with her, Gordon calls Sidney's apartment to come back to help. On his way back across the park, however, a gorilla-suit wearing Sidney runs again into his muggers and they force him to assault a woman in the park, who turns out to be an undercover male police officer. Back at his apartment, Gordon's mother humiliates him in front of Louise at dinner, pulling down his pants and biting his buttocks. This causes Louise to flee into a cab, leaving Gordon on the street with his pants still around his ankles.

A despondent Gordon visits Sidney in jail, who, to both of their surprise, gets off free. The next day, Gordon returns to work, but, tired and unfocused, he represents a client in court with utter incompetence. During this trial, Louise appears at the back of the courtroom and Gordon leaves abruptly to meet her. At the end of his rope, with Louise unable to stand his mother one minute more and threatening to leave Gordon, he returns to his apartment, picks up his mother, packs her luggage, and tells her that they're going to meet Poppa. Gordon drives with his mother and Louise to a series of rest homes, some of which take terrible care of their residents but none of which currently have room. After eventually finding one that will take his mother, Gordon drops her off at the entrance and presents a random elderly stranger as Poppa. Finally free of his mother, Gordon and Louise then drive away joyously.

Where's Poppa? was released in the United States on November 10, 1970, by United Artists.^[11][12][13] Though it did not do well upon first release, it subsequently gained a following, prompting United Artists to re-release it nationally in 1975 under the title Going Ape.^[14][15][16] United Artists chose the title because the film involved various gorilla-related shenanigans.^[7] Where's Poppa? was released on DVD in 2002, and on Blu-ray in 2016.^[17]

In regards to the VHS releases of Where's Poppa?, the Key Video release was the theatrical version, which had its original ending changed to a more 'sedate' finish. The later MGM/UA Home Video release had the original ending restored where Gordon Hocheiser ends up in the bed with his mother. Thus, viewers have their choice of which version they prefer to watch.^{[citation needed]}

Roger Greenspun of The New York Times wrote that if the film "doesn't succeed all the time, or even most of the time, it succeeds often enough, if only by energy and will, to satisfy a taste for comedy that has not had much nourishment this season."^[12] Roger Ebert rated the film three stars out of four and recommended it to those "who want to laugh and like being offended."^[18] Gene Siskel of the Chicago Tribune gave the film two-and-a-half stars out of four and wrote that Klane "has written his screenplay as tho he thought it would be his last (a position which can be self-enforcing). He's crammed the short story (only 83 minutes) with comments on the Army, little-league baseball and Central Park. He should have stayed with his major story premise which is wickedly funny."^[19] Variety wrote that "Many ... will be offended by this black comedy," but "Many others will feel it only hurts when you laugh, and that director Carl Reiner, with a maniac zeal, has pulled off one of the most outrageous and funniest comedies this year."^[20] Charles Champlin of the Los Angeles Times called the film "irreverent, foul-mouthed, vulgar, tasteless, indecent and—for reasons I'm not sure I fully understand—riotously funny."^[21] Gary Arnold of The Washington Post wrote that George Segal was "in really brilliant form" but the film's mix of "self-consciously outrageous" scenes and charming scenes "don't blend, and often the tendency of one style warps or undermines the tendency of another."^[22] Tom Milne of The Monthly Film Bulletin wrote, "Flawlessly scripted, acted and directed, and hovering somewhere between Lord Love a Duck and Little Murders in its delightfully eccentric humour, Where's Poppa? is one of the nicest black comedies in years, as well as the funniest."^[23]

In 1979, a half-hour television pilot was aired on ABC for a proposed series titled Where's Poppa?, starring Steven Keats (Gordon), Elsa Lanchester (Momma), and Allan Miller (Sidney). The series wasn't picked up.^[24][25][26]
