Writer and director Kyle Patrick Alvarez will premiere his second feature film at the Sundance Film Festival this coming Saturday. The Cuban-American director's latest film "C.O.G." is the first movie ever produced based on a David Sedaris essay, with his permission. [Entertainment Weekly describes how Alvarez connected with Sedaris:](http://filmguide.sundance.org/film/13123/cog) > > Hollywood had been knocking on Sedaris's door for years, and he'd always turned suitors away. But Alvarez, whose promising first film, Easier with Practice, was based on a 2006 GQ article by another public-radio raconteur Davy Rothbart, took a more personal approach: he went to a Sedaris book signing. "I waited in line with everyone for him to sign my book after he read," says Alvarez. "I tried not to be aggressive, but I gave him the a copy of my first film and said there were some things I'd like to talk to him about. I was incredibly anxious about it, but fortunately, he really liked the movie." > > They began exchanging emails, with Sedaris asking Alvarez why he specifically wanted "C.O.G." -- which stands for Child Of God -- an essay from Naked, Sedaris's best-selling 1997 collection. "It's not like I went through every Sedaris story and tried to find the one to make into a movie," says the 29-year-old, who also wrote the screenplay. "I liked this story. Had he not written it, and it was another writer, I would still have been incredibly interested and tried to make it into a film. There's a coming-of-age aspect to it that I felt was really unique and particular." Sedaris has yet to see the film. He'll see it for the first time at the [Sundance premiere](http://insidemovies.ew.com/2013/01/12/cog-sundance-poster/) this coming Saturday. "C.O.G." will premiere at [Sundance on January 20th, 2013](http://insidemovies.ew.com/2013/01/12/cog-sundance-poster/). All five screenings of his film are sold out online and only have "wait-list only" availability.
