 While the film was being developed at the Sundance filmmakers lab,  Kieran Culkin (qv) played the role of Scott in all of the  experimental scenes the Martinis shot. When it came time to make the  film for real, Kierans younger brother, Rory Culkin (qv) was  offered the role because Kieran had become too old to play it. After  reading the script and watching the experimental scenes from the  lab, Rory said yes.
