Visible crew/equipment: In the old hospital, Dammers grabs Lucy, and says "You're all the same!" Then Lucy elbows Dammer in the stomach and face, and runs through a doorway from him. As she runs away, the shadow of a camera is clearly cast on the brown door she passes.

Visible crew/equipment: Outside the chapel, when Frank backs into the pedestal the statue begins to topple over. In the shot facing up, as the pedestal falls and Frank puts his arms out to catch the statue, the wires used in this stunt are perfectly visible.

Revealing: At the Fairwater Tuberculosis Sanatorium, when Agent Dammers shoots Frank in his left arm, the white wrapping around his arm, where the bullet holes appear, is visible under Frank's short sleeve.

Continuity: When Mrs. Waterhouse walks into the livingroom and greets her three babies, there is a large area rug in front of the coffee table. However, as the babies fly towards her in the wide shot facing her, that area rug is gone!

Revealing: After Lucy discovers Mrs. Bradley in her bed, as she fights off and runs from Patricia, it is obvious that she wears knee pads for these shots.
