Casting continued through 2009, with Zoe Kazan, Lake Bell, and Hunter Parrish joining in January, John Krasinski in February, Rita Wilson in March, and Caitlin Fitzgerald in June . </P> <P> While the majority of the film is set in Santa Barbara, California, most of the filming--including nearly all of the interiors--took place in New York City . Principal photography began on February 18, 2009 at the Broadway Stages in the Brooklyn borough, where the interior scenes of Jane's house were shot . Several other key locations were used during the first portion of filming in New York, including Picnic House, a large, studio - sized structure in Brooklyn's Prospect Park, where Jane's bakery was built inside; the facilities at Sarabeth's Bakery in the Chelsea Market; and a commercial loft building in New York's Chelsea district, where scenes at Adam's architecture office were filmed in . As Martin was soon to embark on a concert tour to promote The Crow: New Songs for the Five - String Banjo (2009), his schedule required the team to complete shooting his scenes during the first two months of filming . </P> <P> In April 2009, the company relocated to Los Angeles, where cast and crew started filming scenes taking place outside Jane's house, for which a ranch house located in Thousand Oaks in the north of Los Angeles was used . In mid-April, the crew spent a few days filming exteriors in Montecito and Santa Barbara--just days before wildfires took a heavy toll on the area . Additional scenes were taken in front of numerous downtown landmarks, including the Santa Barbara County Courthouse and the El Paseo section . Afterwards, the team returned to Los Angeles for completion of the scenes at Jane's house and for the filming at the Bel - Air Bay Club in the Pacific Palisades neighborhood . In early May, principal photography returned to Brooklyn for completion . For Luke's graduation scenes, shooting took place at St. John's University in Queens and on Park Avenue in Manhattan .

The hotel bar was the interior of a restaurant on Tenth Avenue . Filming eventually completed in August 2009 . </P>
