A look at movies opening this week.

BARNEY'S VERSION


Paul Giamatti won a Golden Globe for best comedy actor thanks to his superior work in director Richard J. Lewis’ adaptation of Mordecai Richler’s prize-winning novel about an ordinary man living an extraordinary life. Rachelle Lefevre, Minnie Driver and Rosamund Pike (“An Education”) play Barney’s three wives, while Dustin Hoffman, Mr. Focker himself, plays Barney’s zany father.


UNDERTOW


There’s been a spate of TV shows and movies of late in which the hero possesses an ability to speak with the dead. Peruvian writer-director Javier Fuentes-León eagerly jumps on the bandwagon with this tale about a deeply religious fisherman (Cristian Mercado) fooling around with the ghost of his gay lover (Manolo Cardona), much to the chagrin of his very pregnant wife (Tatiana Astengo).


SANCTUM


You’d have to be living in a cave not to have heard about this James Cameron-produced 3-D spelunker adventure about a group of underground divers fighting for survival after they get swept up in a flash flood spawned by a typhoon. Allegedly based on a true story, the film features a largely unknown cast (all the easier to quickly kill them off) led by Richard Roxburgh (“Moulin Rouge”), Ioan Gruffudd (“Fantastic Four”) and Rhys Wakefield. Sounds boring, but the locations off the Gold Coast in Queensland, Australia, should be awesome. Alister Grierson directs.


THE ROOMMATE


Remember when Jennifer Jason Leigh rammed that high-heel shoe into Steven Weber’s eye in “Single White Female?” Who could forget it? Well, apparently the producers of this not-so-subtle rip-off did. This time instead of Bridget Fonda as the goody two-shoes, we get Minka Kelly, who makes the mistake of sharing a college dorm room with a deceptively psycho Leighton Meester. At least what the film lacks in originality is more than compensated for by its two attractive stars. Or is it? The film wasn’t screened for critics. So “Roommate” hunters beware.
