Gray Mattershas one of the most adorable casts of any movie in recent years--the combined sweetness of Heather Graham (Austin Powers:  The Spy Who Shagged Me), Bridget Moynahan (Lord of War), Molly Shannon (Year of the Dog), Thomas Cavanagh (Ed), Alan Cumming (X-Men 2), and Sissy Spacek (Carrie,In the Bedroom) narrowly avoids being diabetes-inducing. Gray (Graham) and her brother Sam (Cavanagh) have been best friends forever--so close that they find it hard to date. Gray pushes Sam into asking out Charlie (Moynahan), but when Sam and Charlie hit it off so well they spontaneously decide to get married, Gray finds herself unexpectedly dismayed... but not as dismayed as she is when, on a girls' night out before the ceremony, she and Charlie share a drunken kiss that sets Gray's body tingling.Gray Mattersjuggles a lot of emotional issues; the sibling interconnectedness problem doesn't flow smoothly into the coming-out story of the movie's second half. But sprinkled throughout are charming scenes and wonderfully deft moments that make the story's clumsy missteps all the more baffling. There's no question that Graham is a star who just can't seem to find the right vehicle;Gray Matterswon't be her breakthrough, but it's further evidence of her significant appeal.--Bret Fetzer
