Meyers creates a nifty setup. Nicholson as Harry Sanborn is a rich record company owner and Amanda Peet as the sexy Marin finds him charming and fun, as do other young women he dates. They are about to have a weekend of lovemaking when Marin's mom (Erica) turns up with her friend Zoe (Frances McDormand), who tells off Harry over dinner in a diatribe about how unfair it is that older men date young women and leave older ones to face lonely nights. Erica, a successful playwright who has come to terms with her lifestyle, resents being made to seem so vulnerable.

The screwball comedy syndrome kicks in, and although there's the required hostility at first, an attraction develops between Harry and Erica after Harry has a heart attack and stays at the beach house while recovering. Meyers extracts plenty of comic mileage out of the age situation. Harry is huffing and puffing, but Keaton looks great in her role, and even gets to do a nude scene. She gives a smashingly funny and even touching performance, one of her best. Nicholson is as entertaining as he usually is.

The kicker is that Keanu Reeves as the young, handsome doctor who treats Harry for his heart problems falls head over heels in love with Erica, who now can be the older woman with the young romantic stud. Whom will she choose, the older suitor or her new young, adoring lover?

Before we get the answer, "Something's Gotta Give" provides abundant entertainment, thanks to the acting of the old pros, good performances by the younger Peet and Reeves, and funny confrontations and situations, plus a trip to Paris. Meyers writes good dialogue, such as Harry saying: "I have never lied to you--I've always told you some version of the truth."
