Charlyne Yi's "documentary" about finding love, that turns into a romantic comedy, or something else entirely, depending upon how much you know about the situation between Yi and Michael Cera, made its debut at the Sundance Film Festival and won a screenwriting award. You've heard about it. You've read about it. Now here is the first official trailer for Paper Heart. Looks more than cute. Trailer includes appearances by Seth Rogen and Demetri Martin. Paper Heart arrives in theaters Aug. 7, 2009. Enjoy!
