A film noir set mostly in broad daylight, “Don McKay,” writer-director Jake Goldberger’s mild riff on “Double Indemnity,” etc., works best as a showcase for its veteran cast, particularly Elisabeth Shue in a playful perf as a small-town femme fatale faking terminal illness. As the titular homme futile, exec producer Thomas Haden Church displays aptly geeky gullibility in a film that most resembles John Dahl’s twisty cable/theatrical hybrids of the mid-’90s. Unlike Dahl’s “Red Rock West,” though, Goldberger’s oddly laid-back thriller will stick exclusively to smallscreen slots.
Pushing an electric broom in Nowheresville, high school janitor Don (Church) is summoned to the town of Mount Raven by his childhood sweetheart Sonny (Shue), who looks to be the healthiest cancer patient alive. Suspiciously begging to spend the “rest of my short life” with a milquetoast loser, sexy Sonny turns up the body heat but somehow can’t get Don to the altar as required by her gold-digging plot. Despite the blackly comic appearance of a corpse about halfway thru, the pic doesn’t gather sufficient steam until its surprise-packed final reel, in which Melissa Leo earns laughs as Sonny’s independently scheming nursemaid.
