“Send Me No Flowers.” MCA. $59.95. Rock Hudson and Doris Day were nearing the end of their reign as Hollywood’s box-office king and queen when they made this film. It’s from a hit play about a hypochondriac convinced he’s dying--and under Norman Jewison’s direction, with a cast that includes their usual second banana, Tony Randall, it begins quite well. Day has her usual sprightly bounce (Paul Lynde, as a flirty cemetery salesman, is even bouncier), Randall has his usual dry finesse--and Hudson shows some subtlety as the glumly deceived patient. But midway through the movie collapses into shallow infidelity farce, dribbling off in clumps of plastic-hearted sunniness. Still, for at least the first half-hour, something about Day and Hudson summons up the Kennedy years--and compulsive upward mobility--better than we might have thought at the time.
