In Paris, the weird traveler Mr. Koberman (Féodor Atkine) registers in a small pension nearby the Seine River owned by the grandmother (Micheline Presle) of the boy Douglas (Adam Negley). The strange habits and the aversion to silver of Mr. Koberman raise suspicions to the little Douglas that he is a vampire. One morning, when the student Miss Treadwell (Kate Hardie) does not return to the inn, Douglas spies the guest and concludes that he is a vampire with tragic consequences.
"The Man Upstairs" is another weird and ambiguous episode of "The Ray Bradbury Theater". The boy Douglas is one of the creepiest characters of this series and his final decision is dreadful. My vote is six.
Title (Brazil): "The Man Upstairs"
