1 revealing mistake - chronological order
Directed by: Matthew Robbins
Starring: Jessica Tandy, Hume Cronyn, Elizabeth Pena, Frank McRae
Continuity mistake: In the scene on the roof when the local hoodlum is attempting to take on the flying saucers you see the scene from two points of view. There are four people watching the local hoodlum getting fried. From the front, from left to right you see an old guy; a tall black guy; a women in pink and then a young guy with lots of hair. When seeing the scene from behind these watchers, you only see the old guy and the guy with the all the hair. Each time the angle changes the tall black guy and the women in pink are there.
Pamela: It's old and depressing.
Mason: It's reality.
Pamela: This is the '80s! Nobody likes reality any more.
Trivia: This movie was originally supposed to be part of the TV series "Amazing Stories" but Steven Spielberg like the story so much that he decided to make it a full length film.
