Cary Grant's devotees-and they are legion--will come to his defense even under the most trying of circumstances (I'm the same way with actors and actresses I admire). Grant's performances are often lovingly called "droll" and "relaxed" while I see them as unimaginative and one-dimensional. He's not at home on-screen so much as he inhabits the space he's in, and I unavoidably begin imagining different actors in his roles (consider Rod Taylor opposite Audrey Hepburn in "Charade"!). "Houseboat" is no exception, but it's a good movie. Grant is overanxious, as usual--and pushy or needling with the kids involved--but he's well-placed as a love-interest opposite Sophia Loren (whom he was dating just prior to the filming but not during). At first glance, "Houseboat" looks like the worst type of sitcom: stern father gets saddled with his estranged children, later hiring a governess who is really a runaway from high society. Grant plays the dad with consternation and suspicion (according to the script, of course, though Grant is typically like this). He goads his kids into being more than what he sees on the surface--and when his son finally pushes back, it seems an exceptionally realistic reaction. As for Sophia, who basks in her movie-star close-ups: she takes a cartoonish character (which is written like a cynical refugee from "Roman Holiday") and gives the lady a big heart. Her bonding with the children (and with Grant) is a treat and, while I wasn't convinced it would all work out happily, I was reasonably entertained. **1/2 from ****
