A genuine charmer by George Roy Hill, a director best known for such ersatz charmers as Butch Cassidy and The Sting. His crowd-pleasing instincts have been subsumed by a bracing technical assurance here; the contrivances are still there, but they’re presented with a smooth and rare professionalism. The plot of this self-styled trifle recalls one of Hill’s early successes, The World of Henry Orient, in the way its adolescent romantics (between Diane Lane and Thelonious Bernard) are played against a background of grown-up culture and sophistication. Laurence Olivier, as an aging rake, is mannered but pleasant, and Pierre William Glenn’s bright cinematography adds the right touch of continental exoticism. With Arthur Hill, Sally Kellerman, and David Dukes as Steven Spielberg.
