Operación reno

John Frankenheimer follows up his great comeback film, "Ronin," with "Reindeer Games," a flawed but efficient thriller that recalls his earlier "52 Pick-Up."

Freshly paroled ex-con Rudy Duncan (Ben Affleck) assumes the identity of his cellmate, Nick (who misses out on his parole when he is taken out during a prison riot), when Rudy falls for Nick's gorgeous pen-pal, Ashley (Charlize Theron). The ruse goes awry when he is also mistaken for Nick by a gang of thugs (headed by Gary Sinise) who recruit him in their planned heist of an Indian casino at which Nick had been employed.

Like "52 Pick-Up," "Reindeer Games" has a central character whose flawed behavior puts him at the mercy of dangerous individuals who conceive a scheme that spins out of control. "52 Pick-Up" was successful because the entire cast, beginning with Roy Scheider as the trapped hero, was equal to the task of bringing the grittiness of the material to the screen. The one significant problem with "Reindeer Games" is the casting of squeaky-clean Affleck as its central character. Through no fault of his own, Affleck looks like a lightweight alongside a supporting cast that includes Sinise, Clarence Williams III, Danny Trejo, and Dennis Farina -- all actors who look like they have lived a little. Affleck cuts a profile similar to that of Scheider, but without the lived-in look that made him convincing as someone who would be able to go toe to toe with his tormentors.

"Reindeer" is helped greatly by the performance of Theron, who, while also young, always has been able to project a more adult presence like the young Kathleen Turner. Credited more for her on- and off-screen glamour, Theron often is underrated as an actress. Here she conveys equal parts sweetness, intelligence, dismay, and ferocity. Of course, she also livens up her sensual scenes. For many actresses, nudity itself is the extent of their sexuality, but Theron generates heat simply by looking comfortable and bringing an unforced quality to the proceedings.

The other major plus is Frankenheimer's direction, which turns an adequate screenplay into a solid thriller. He keeps the story moving and handles the action scenes economically, avoiding the excesses of Michael Bay, Simon West, and other directors of MTV-inspired fireball-fests. As in "Ronin," the action actually stays within the bounds of plausibility, which makes them more involving.
