It’s rare that two actors are expected to carry an entire picture, but this winsome lark with Martin Short and Annette O’Toole is predicated on just that, and succeeds delightfully. The encounter is both archetypal and very contemporary: it’s their third date, each of them has high hopes, and both have things to conceal from each other. Armyan Bernstein, who wrote One From the Heart, collaborated on the script with Gail Parent and directed, and Lawrence Kasdan, of all people, produced, but it’s Short and O’Toole who carry the show throughout; all but a few of the movie’s 96 minutes are devoted to the date, and they keep it fresh, sexy, and unpredictable. It’s a nice demonstration that the most overworked of comic formulas can still work if sparked with the right insights and personalities. (JR)
