13 GOING ON 30

When you watch a body-switching comedy such as Big or Freaky Friday, you know immediately that the movie is going to require a huge suspension of disbelief; these are comedy fantasies, after all, and bitching about logic and realistic plotting is the surest way to kill your good time.

CAST AWAY

In Cast Away, Robert Zemeckis' most fully satisfying work in ages, Tom Hanks stars as Chuck Noland, a FedEx engineer for whom the world can't move fast enough; he's obsessed with time-saving, whether it be with associates in Moscow or friends at home. Before boarding a plane for a business conference, he even goes so far as to give his girlfriend (Helen Hunt) a wrapped engagement ring, instructing her to open it when he returns. (He saves lead-in time on its actual presentation.) But somewhere over the Pacific, the plane crashes (in one of cinema's most terrifying airplane disasters), and Chuck is washed up on a deserted island with little hope of escape or rescue; suddenly, he has all the time in the world, and the film, which had previously been lightning quick, slows down to a crawl.
