Three clips from I Love You, Man have come out and Rashida is in the first one. It's Red Band so NSFW.
"The "Speakerphone" clip displays the scene when Rashida Jones's Zooey calls her girlfriends to tell them about her getting married to Paul Rudd's Peter Klaven and puts them on a speaker phone with Klaven listening. While discussing about her wedding plan, her friends switch the topic to her sex life with Klaven."
See the others at the source. "Boat Race" is gross but v. funny.
Release date: March 20, 2009
