Robinson and producer Lynda Obst sent Ricky Gervais the script out of the blue in the hopes that it would spark his interest. Gervais loved it and eventually flew Robinson to London to retool the script and make the movie. Robinson’s original idea for a feature film grew from a skit he wrote about two people on a date who do not have the ability to lie. He later expanded on the idea for more skits with the same premise and then adapted them into a full film script. Media Rights Capital and Radar Pictures financed the film. However, 1821 Pictures sued Radar Pictures for breach of contract over failure to pay a $450,000 production fee. Shooting took place primarily in Lowell, Massachusetts; location shoots also took place in Quincy, Andover, North Andover, Sudbury, Tewksbury, Boston, Massachusetts, and Haverhill, Massachusetts.
