A few weeks ago, Columbia released a red-band trailer for the upcoming very R-rated comedy Bad Teacher. Today, a cleaner theatrical trailer has been released. It’s pretty much the same as the red-band, with far less foul language and a couple of added scenes. Seeing as how this comedy seems to be predicated on the fact that it’s really dirty, the clean trailer doesn't really work as well as the red-band one.Directed by Jake Kasdan (Freaks and Geeks, Walk Hard), the film features a stacked comedy ensemble that includes Cameron Diaz, Justin Timberlake, Jason Segel, Phyllis Smith, and Lucy Punch. Diaz plays a pretty filthy teacher who decides to whip her students into shape in hopes of winning a cash prize that she will put towards breast implants to hopefully woo the Timberlake’s “nice guy” character. Hit the jump to watch the trailer. Bad Teacher opens on June 24th.Here’s the trailer (via Yahoo!):

Some teachers just don’t give an F. For example, there’s Elizabeth (Cameron Diaz).  She’s foul-mouthed, ruthless, and inappropriate.  She drinks, she gets high, and she can’t wait to marry her meal ticket and get out of her bogus day job.  When she’s dumped by her fiancé, she sets her plan in motion to win over a rich, handsome substitute (Justin Timberlake) – competing for his affections with an overly energetic colleague, Amy (Lucy Punch).  When Elizabeth also finds herself fighting off the advances of a sarcastic, irreverent gym teacher (Jason Segel), the consequences of her wild and outrageous schemes give her students, her coworkers, and even herself an education like no other.
