The original ending had Shawn find Happy dying in the wheat field. The field was due to be harvested and Watson knew he couldn't cast someone in time so the ending was changed to Happy being found dead in the grounds of the high school he is seen entering. Feeling that this was rather flat he created the Tigger's Barn scene and 2 new characters. This ending went through 2 incarnations, one which would bring back Paul Michael McIntosh from Shawn's Dark Xmas (2012), but no one could be bothered committing. The fifth and final ending written, as filmed, is a combination of the second and fourth written endings.
