It's hard for me to imagine that even Production Code audiences of 1951(note the newly- weds' unlikely twin beds) found this silly exercise anything more than occasionally titillating. I guess the movie was intended as a romantic comedy. The premise of a woman (Young) with two distinct personalities depending on whether she's sleepwalking may have sounded promising, but the result plods along in uninspired fashion minus either bounce or charm. Apparently, supporting players like Backus and Max are supposed to provide the chuckles, but it's really only Irene Ryan as nurse Kay who comes through in lively fashion. From his credits, it looks like director Sale was a much better writer than director or comedy coach.
It also looks like Young is having a good time vamping it up in the wanton half of Nora's split personality. The overt sexuality probably comes as welcome change from her typical good girl roles. However, despite the good-humored approach, the result is more ludicrous than funny. Nonetheless, she does get to model 1951's latest fashions, a big thing for Young as her TV show attests. Unfortunately, that fine actor Joseph Cotten is reduced here to little more than a male manikin in a clearly secondary role.
To me, the most intriguing aspect is what blacklisted film-noir and scheduled director Jules Dassin (Brute Force, 1948; Thieves Highway, 1949) would have done with the goofy premise and a very proper Young. If ever there was a mismatched movie pair, this is it. So it's no surprise that one of the two (Dassin) ended up having to leave the project (according to IMDb). Anyway, it's still a curious question what the highly serious Dassin would have done with such frothy material. Whatever the result, it's bound to be more interesting than this unfortunately forgettable 80 minutes.
