Martin Donovan, a consistently fine and busy actor in films ("The Opposite of Sex," "Insomnia") and on TV ("Weeds,""Boss"), adds screenwriter and director to his resume with disappointing results in the somber, would-be thriller "Collaborator."
Oddly, it's Donovan's performance here that proves the movie's weakest link, though his writing and helming tie for a close second. As Robert Longfellow, a conflicted playwright who flees New York for his mother's (Katherine Helmond) L.A. home after his latest play flops, Donovan sleepwalks through much of the film; it's as if he's exhausted from wearing those extra two hats.
Costar David Morse fares just a bit better as the damaged, rednecky Gus, Robert's childhood neighbor who, at 57, still lives across the street with his long-suffering mom (Eileen Ryan).
The film's engine — wanted criminal Gus, armed with beers and a gun, takes Robert hostage in his mother's house — sputters when it should hum with tension and menace. But Gus, a fairly unvigilant captor, spends more time lost in hollow wordplay with Robert, defending the Vietnam War or chatting by phone with Robert's actress ex-lover (Olivia Williams) than seriously tightening the screws.
