Two similar Christian religious statues are shown in the convent in the film. One is on the floor in the blue room where Dean first meets Sister Clodagh to talk business. It is hidden behind the nuns where they enter to speak to Dean. Another very similar statue, but bearing a cross (possibly St Faith), is shown next to Dean as he converses with Sister Clodagh. It has some packing material (straw) on it (19:02). Later on, this second statue is shown being unpacked from its crate by Dean and a servant to be placed above the doorway leading to the yard (27:27).
(at around 1 min) There is a statue of the crucified Christ, complete with the requisite wounds. however, the wound on his chest is on the wrong side - it is always shown on the left side; this one is on the right. Note that this is merely an artistic convention; the Bible (Jn 19:34) does not mention which side was pierced.
Near the beginning the bell for the future school and infirmary is rung. As the bell swings forward towards the viewer it partially disappears behind some scenery that depicts landscape which is supposed to be behind the bell.
