In the mid 80s in the UK I watched a kids’ movie on TV in colour about a group of kids/teenagers who were able to travel through electronic devices. They could just kind of leap into them and travel at the speed of light to different places, and possibly through time as well. I only have a clear memory of one of the final scenes where the protagonist is sentenced to death and given one last request before execution. They choose to watch TV one last time as a cunning plan to escape. The executioners say something like “it’s 5 in the morning – there’s nothing on TV at this time,” but the wish is granted anyway. A TV is wheeled to them and the kid jumps into it, evading execution.
I’d be so grateful for any help with this.
