Revealing mistake: You can see the wires on the handgun pointed at the two extraterrestrial children when the bad guys are staring in shock at the "floating gun."
Escape to Witch Mountain (1975)
1 revealing mistake
Directed by: John Hough
Starring: Donald Pleasence, Eddie Albert, Ray Milland, Kim Richards
Continuity mistake: When the gun is telekinetically pointed at Deranian and his henchmen, Jason and the kids use this to escape and drive past both men. In the next shot, when the gun is seen still suspended in mid-air, the camper is seen right behind it.
Jason O'Day: Ahhhh...so that's it. You're nothing but a conniving pair of undersized land pirates.
