In the 1972 chiller "The Other," 11-year-old, identical twin brothers Niles and Holland Perry are virtually indistinguishable from the outside; personalitywise, however, they are as different as day and night, right and wrong, good and...evil. While Niles is content to use his imagination to play games and while away the lazy summer at his extended family's home in rural CT, in 1935, Holland is perpetually making trouble. But soon enough, those childish pranks turn decidedly more sinister, and even deadly. Indeed, viewers will likely be struck by the thought that Holland makes little Rhoda in 1956's "The Bad Seed" look like a perfect little angel by comparison. But wait...right around the film's 70-minute mark, screenwriter Thomas Tryon pulls the rug out from under us, landing us in even stranger waters indeed. From there on, this pleasant, idyllic film becomes increasingly dark and disturbing. Playing the two brothers, Chris and Martin Udvarnoky have been ideally cast in this, their only film. Giving one of her very few film performances, stage actress Uta Hagen is just marvelous as the boys' doting and too encouraging grandmother, and Diana Muldaur, playing their invalid mom, looks even prettier than she had four years earlier in the classic "Star Trek" episode "Is There In Truth No Beauty?" Fans of the late John Ritter may also be interested to see that actor here, close to the beginning of his career. And kudos to director Robert Mulligan and DOP Robert Surtees, whose evocation of the mid-'30s is very lovely and sure-handed. This warm, almost pastoral atmosphere leaves the viewer quite unprepared for the nastiness that eventually comes; the cozy backdrop only makes the later psychological explorations and family revelations feel all the more icy. This film will surely leave viewers with an urgent need to watch it again, and a repeat viewing does reveal how skillfully the filmmakers have hinted at and yet artfully evaded the picture's major secrets. As for that final shot of young Niles' face at the window, let's just say that it should chill you to the bone on a hot summer night....
