Diaz, Timberlake star in ‘Bad Teacher’

When: Opening Friday at local theaters

Cast: Cameron Diaz, Jason Segel, Justin Timberlake, Lucy Punch

Director: Jake Kasdan

The story: After she’s dumped by her sugar daddy, a foul-mouthed, gold-digging junior high teacher goes after a colleague — a move that puts her in competition with a model faculty member across the hall.

The buzz: The tabloid spotlight has been on the reunion of real-life exes Diaz and Timberlake in "Bad Teacher," but word is that the breakout presence is Brit wit Punch, who reportedly steals the show as the goody-goody Miss Squirrel. It’s nothing new; Punch delivered hilariously fearless performances in last year’s "Dinner for Schmucks" remake and as Anthony Hopkins’ much-younger paramour in Woody Allen’s "You Will Meet a Tall Dark Stranger."
