He also stated months before the movie even came out that this would be a movie where the main characters don't fall in love, and both he and Ginnifer Goodwin have stated on different occasions that the ending exchange was indeed meant to be platonic, a fact that apparently evaded Jason Bateman, who thought the exchange was supposed to be a romantic one.
