Tom Flynn’s scintillating yet serious 1993 romantic comedy stars Peter Gallagher (right) as a young Texan on a stay with his cousin (Jon Tenney) in a Chicago suburban home. Tenney and his two roommates (John C. McGinley and Tom Sizemore) are all dedicated--and potentially nasty--pranksters. Flynn comments on the all-American tendency of men to grow older without growing up as Gallager, meanwhile, finds his cousin’s girlfriend (a radiant Suzy Amis, left), propelled into his own arms. “Watch It” proceeds with the brisk dispatch of high comedy, deftly contrasting moments of pain with inspired hilarity. With scene-stealer Lili Taylor as Amis’ spunky assistant (TMC Sunday at 10:55 p.m.).
