LOS ANGELES — Not that anyone was exactly clamoring for it, but “The Collection” is a sequel to Marcus Dunstan’s little-seen 2009 horror film “The Collector.” The director and his co-screenwriter Patrick Melton have written four of the “Saw” films, and this similar exercise in gratuitous sadism and gore follows roughly the same template.

But this nastily efficient chiller offers some effective chills along the way.

Attending the party is beautiful rich girl Elena (Emma Fitzpatrick), who manages to survive the grisly goings-on long enough to open a trunk and rescue Arkin (Josh Stewart), who previously survived the first film. Although he manages to make a daring escape by diving out of a window, she’s taken prisoner by a masked killer who totes her back to his lair.

Unfortunately for Arkin, Elena’s father (Christopher McDonald) has hired a crack team of mercenaries to find his little girl, and he makes Arkin lead the way.

Led by the father’s right-hand man Lucello (Lee Tergesen), the team ventures into the Collector’s house of horrors located in the “Hotel Argento.” There they encounter a series of booby traps. They’re also forced to contend with many of the still-living captives.

Most of the film’s running time is consumed with this cat-and-mouse game, with the proceedings resembling one of those elaborate haunted house attractions that spring up every Halloween.

Running a taut 82 minutes, the film maintains a considerable degree of tension throughout.

But director Dunstan is clearly mainly interested in ratcheting up the gore content via endless scenes of bodies being dismembered, impaled or blown up.

Unfortunately, the Collector simply isn’t a very interesting screen villain. Clad in a black mask that reveals only his eyes and mouth, he mainly communicates by heavy breathing.

The performers go through their masochistic physical paces in admirably committed fashion, with Fitzpatrick proving a plucky screen heroine. But despite their efforts, this latest example of the increasingly exhausted torture genre will be of little interest to any but its most obsessed fans.
