Revealing: When Mr Kipps comes back in into the house after seeing the ghosts of the children in the front garden, he looks down and sees footsteps. The error is the footsteps are far too uniform and equally spaced at regular intervals to look natural. It looks as though a template has been used to print them on the floor.
Continuity: Daniel Radcliffe's facial hair goes from 2 day stubble to clean shaven throughout the movie. About midway through it is very noticeable. He is by himself in the Marsh house, for the 2nd time I believe, and in every shot he has 2 day stubble. However when it cuts to a close-up he has a near-perfect shave.
