As a light, but exceptionally long, rendering of the well-known story of the Frank family and their companions hiding from the Nazis, this film is adequate. It gives a good view of the crampedness of the quarters they shared and some of the harrowing events that occurred while they were there. But it is told in a relatively breezy way. Aside from going through the motions to keep from being found, there’s not as much of a sense of both the danger and tedium that had to exist for such a long period of time together. Millie Perkins is not particularly believable as a young teenager, a bit too cute and precious. On the other hand, Joseph Schildkraut as Otto Frank and Shelley Winters as Petronella Van Dam bring real emotion to their roles, the former as a father trying to keep everyone safe and the latter trying to hold on to life as she once knew it.
