* TheDanza: Liam Neeson as "Randy Father Liam". Presumably this was done on purpose, as the character from the novel was actually named Father Bernard.
* DawsonCasting: Cillian Murphy was about thirty when he played the teenage-to-young-adult Patrick/Kitten. Admittedly the film spans several years, so the age discrepancy isnít quite so bad by the end of the movie. Plus he ''looked'' a good deal younger than he was. But he is still only two years younger than [[PlayingGertrude the actress who plays his biological mother]]!
