Mel Coplin (Stiller) is your average neurotic New York entomologist searching for his birth parents so he can finally name his four-month-old child and make love to his wife. Tagging along on his bumpy ride are his wife Nancy (Arquette), a beautiful quirky adoption agency shrink (Leoni), and a pair of bisexual FBI agents. The excellent cast also features Moore as Mel's bra-baring adoptive mother, Segal as his weirdly paranoid adoptive father, and Alda and Tomlin as hilarious send-ups of ex-hippie mentality. As events spin madly out of control, every type of relationship is satirized, and every character is left in their underwear. This is director Russell's first big-budget movie, and is as close to a vintage screwball comedy as you'll see in the '90s.
