Dreamworks has released the official movie trailer for Along Came Polly director John Hamburg’s new comedy I Love You, Man, which stars Paul Rudd as a newly engaged guy sets out to find the perfect “Best Man” for his wedding. The film costars Jason Segel, Jaime Pressly, Andy Samberg, Jon Favreau, and Rashida Jones. I’m a big fan of many of the actors involved, but I just didn’t find the trailer all that funny. I also wasn’t a fan of Along Came Polly either. Leave your thoughts in the comments below.

Austin, Texas — December 15, 2008 — The South by Southwest (SXSW) Film Conference and Festival announced today that the DreamWorks Pictures film “I Love You, Man” will be the 2009 Opening Night film. The De Line Pictures comedy, co-written and directed by John Hamburg (“Along Came Polly,” co-writer of “Meet The Parents,” “Meet The Fockers,” and “Zoolander”) stars Paul Rudd, Jason Segel and Rashida Jones. The film centers on a man who, upon getting engaged, realizes he has no close male friends and must find someone to be the Best Man at his wedding. The South by Southwest Film Conference and Festival runs March 13 – 21, 2009 in Austin, Texas.

“We are thrilled to have ‘I Love You, Man’ kick off the 2009 festival. The film is the perfect representation of the kind of smart and unconventional humor that SXSW audiences flock to,” said Film Conference and Festival Producer Janet Pierson, “and we are happy to welcome back SXSW Alumni Paul Rudd and Jason Segel.” Rudd appeared in three films at the 2007 Festival (“Knocked Up,” “The Ten” and “Diggers”) and Segel attended in 2008 with “Forgetting Sarah Marshall.” In true SXSW synergy where film, music and new media intersect, Rashida Jones’ father, legendary music producer Quincy Jones, will serve as Keynote speaker for the SXSW Music 2009. 2008 SXSW Opening Night film “21” opened theatrically to $24.1 million following its highly successful debut at the festival.

“I Love You, Man” follows Peter Klaven (Rudd), a successful real estate agent who, upon getting engaged to the woman of his dreams, Zooey, (Jones), discovers that he has no male friend close enough to serve as his Best Man, so he embarks on a series of bizarre and awkward “man-dates,” before meeting Sydney Fife (Segel). But the closer the two men get, the more Peter’s relationship with Zooey suffers, ultimately forcing him to choose between his fiancée and his newfound “bro,” in a story that comically explores what it truly means to be a “friend.” The film opens wide on March 20th, 2009.
