"Three Bad Sisters" (1956) is a noir with a very original story that makes for enjoyable viewing. It's exaggerated enough to be fun without being so far out as to be ridiculous. John Bromfield stays right on top of his situation throughout, showing lots of good sense, something that makes the whole story much more logical and convincing. Nonetheless, there's never a dull moment. He's constantly putting out fires because every member of the family that he gets involved with supplies constant challenges to him.
Bromfield's a pilot whose plane has crashed, and his passenger, a rich guy with great undeveloped land, has been killed. This man actually seized the controls and committed suicide, so Bromfield was lucky. He leaves three daughters (the sisters) and their aunt (Madge Kennedy) to fight over the estate. The psychotic sister (Kathleen Hughes) easily draws Bromfield into the situation because he hopes to recover his losses (the airplane and reputation). The neurotic sister (Sara Shane) is engaged to the lawyer (Jess Barker) for the estate. Hughes wants Bromfield to break this up by romancing Shane; her designs on Shane evolve to much worse. The nympho sister (Marla English) delights in stealing men from her sisters. Hughes has no use for her either. Kennedy thinks Bromfield is a rank opportunist after the family's money and constantly berates him and plots against him.
There is more than enough going on here to last the 76-minute running time. The novelty and freshness of the story combined with vigor in the acting are what separate this movie from the herd.
