The siblings Sara (ANNASOPHIA ROBB) and Seth (ALEXANDER LUDWIG) have some myterious paranormal powers. But they still need a nanny: and that’s Jack Bruno (DWAYNE JOHNSON) the taxi driver’s job!

I think that the movie Race To Witch Mountain is a good film to educate children about science fiction: they watch it in their childhood and are addicted to sci fi once grown up!
