Bruce Joel Rubin, the writer of Jacob’s Ladder and Ghost, is both writer and director of another spiritual parablethis one about a prospective father (Michael Keaton) who discovers he has cancer and may not live to see the baby; he decides to make a video about his life to leave behind. Nicole Kidman plays the wife and mother, and she and Keaton both make the occasional longueurs of this sincere and sensible if fairly predictable story worth sitting through. Surprisingly, there’s a fair amount of comedy along the way, and far from being depressing the movie offers as sunny a prospect of coming to terms with death as one can imagine. Haing S. Ngor plays Keaton’s insightful Chinese doctor and spiritual guide, and the other costars include Bradley Whitford, Michael Constantine, and Rebecca Schull. (JR)
