After the scene in which the identity of the old, blind beggar is revealed to the audience the screen fades to black. As the next scene (with Squire Sedgefield sitting writing at his table) commences the sound of galloping horse hooves can be heard and the ghost-like image of a horse and rider can be seen moving across the screen towards the camera seemingly passing through the candelabra on the table. This is not a ghost but a goof. This is an overlap from a second scene of George Heeningham riding to deliver the letter to the Colonel that must have been edited out of the final version of the film. The horse can be heard and seen at around 27 minutes 15 seconds into the film.
(at around 1h 27 mins) At the climax of the film Philip Wraydon rubs his hands together with glee and cackles wildly at the plight of the hero. However, when the shot changes to a close-up of Philip throwing the switch to start the mechanism we can clearly see the actors mouth is closed and his lips are not moving even though he is still heard cackling away.
