While we are on the subject on that movie. In the music video for the song When You Come Back To Me Again (from the movie, Naturally), there's a scene where a man is running through a tunnel when a object (not sure what it is) explodes and he has to escape the tunnel before he gets burned to death. Does anybody know what part of the movie that scene is from.

It was a movie where there was this guy with an old radio/microphone setup whose father died in a fire (he was a fireman, and he took the smoky route out of a house instead of the fiery route and suffocated; the correct choice would have been the fire on the right). Then one day the aurora borealis or something allows the radio to communicate with a past version of itself, and he tells his father who he is (and helps his brother found Yahoo in the process). He saves his father's life, but it makes his mother a target of a serial killer, and she is retroactively killed. Then, with the confusing cooperation of the past version of himself and his past father, they eventually take the killer down (the climax involves the killer's hand disintegrating, and his father shooting the killer in the back). Then the aurora fades and they live happily ever after.
I watched the Hungarian dub, though, so I don't know how popular this is in the West.
