Hi, I saw this film on tv in the late 70s when I was a child. It’s a James Bond movie I think. It would be either roger moore or Sean Connery. They’re on a boat watching a screen, when something scary happens to a person on the screen. I can’t remember what. I just remember being a bit freaked out. I remember my grandmother trying to calm me down by saying “don’t worry, their tv just went wrong”. Any ideas??
