Visible crew/equipment: In the scene where Graham and Reddy are talking at the side of Reddy's car window, Reddy speeds away and you can clearly see the reflection of the camera on the car and in the car's tinted windows. (00:54:50)
Signs (2002)
1 visible crew/equipment mistake
Directed by: M. Night Shyamalan
Starring: Mel Gibson, Joaquin Phoenix, Abigail Breslin, Rory Culkin
Continuity mistake: When the deputy sheriff comes out of the house, her ink pen is sticking through the hole in her pocket flap but not in the pocket itself. After she turns around at the car, her ink pen is inside her pocket and not "flapping" loose as it was just a split second before. (00:21:15)
Graham Hess: Everybody in this family needs to just calm down and eat some fruit or something.
Trivia: Ray Reddy (the man who accidentally killed Graham's wife), is the writer/director/producer of the film, M. Night Shyamalan.
Question: Do the individual aliens have cloaking abilities? It seemed at that the dogs were reacting to something that the people could not see. Were they smelling cloaked aliens? Were they going crazy to protect their human owners and that was misinterpreted as an attack on the people? I thought they are walking around at least invisible at times to do their work without detection. I may be wrong on that.
Answer: The aliens were not cloaked, not invisible. They had a chameleon-like ability to change their appearance to match their background. Recall the alien's fingers turning plaid when he held the boy. They seem to be that green color when not camouflaged. The better senses of the dogs did allow them to detect the aliens. However, one of the effects of alien presence noted in the movie was a change in personality; that is what happened to the dogs.
