Written by Emeric Pressburger and directed by Michael Powell, this family-friendly tale follows young John as he loses his pet mouse during a school trip to the Tower of London. Vowing to find the rodent later, he returns to school and is sent home after he falls asleep in class. But after an accident aboard the subway turns him and the other passengers yellow, he embarks on a strange─and dreamlike─adventure. Mark Dightam, Robert Eddison, Helen Weir star. 54 min.
