I should also state that it's not just a frame or two, but the 'double image' starts when the house is about in the middle of Dylan's body, until it gets a tad past his shoulder. When you watch the movie full screen, it's very easily noticable.
In this scene, you can see a double image of the house in the background. I assume that this was an error that the director didn't catch when filming, with the bright house reflecting off the camera lense making a ghost image appear in front of the actors. Is this correct, or was this ghosting...
