Tales from the Crypt 6.09: "Staired in Horror" (1994) directed by Stephen Hopkins
A fun piece about testing the limits of a curse. In this case, a cheating woman is cursed to be immortal, but ancient-looking on the first floor of her house and younger-looking and attractive on the second. For any men in the house, the reverse is true. When a good-looking convict decides to hide in her house, she discovers the middle of the staircase is the perfect place for the both of them. This being TftC, neither of them manage to stay in this perfect spot for very long before things go as wrong as possible.
