Delightfully silly beneath its earnestness, Mortal Passions revels in the amoral, murderous frustrations of a beautiful young wife (Krista Errickson) doing her best to bed and bounty any and all of the men in her life.
First, there’s the likable rich husband (Zach Galligan), long on suicidal impulses and short on immediate career goals. Galligan suspects Errickson is having an affair. Indeed, being so innocent, he would be shocked to know what a tryst it is, with Errickson enthusiastically bound to the bedposts by her lounge-lizard boyfriend (Luca Bercovici) as the two of them plot murder.
The scene is undone by the appearance of Galligan’s older brother (Michael Bowen), even more psychotically over-protective than they were when they were little. Errickson has an affair with him, too.
There is absolutely nothing predictable about this wonderful group of loonies, and director Andrew Lane never lets slip where he and the tightly wrapped script are taking them.
