So what if it set us on the hysterical ride toward Omen IV? Roman Polanski’s ROSEMARY’S BABY (1968, Paramount, R, $39.98) — newly letterboxed on laserdisc — is the wittiest horror film this side of Psycho…. There’s no forgiving the Rain Man-cheap plot work of LAMERICA (1994, New Yorker, unrated, $89.95, subtitled) — slick young pig redeemed by road trip with wise idiot — or denying director Gianni Amelio’s talent for stark neorealist imagery…. Paul Simon fans can celebrate the regrettable Capeman‘s Broadway demise with PAUL SIMON: GRACELAND (1997, Rhino, unrated, $19.95), a documentary about 1986’s album of the year…. Skater Katarina Witt slips up in THE ICE PRINCESS (1997, Winstar, unrated, $19.98), a wig-laden Cinderella on ice.
