Ghost Writer.

Rupert Cragley, an aging curmudgeon porn critic with a heart condition is warned by his doctor to stop watching dirty movies that might excite and then kill him. But even if Rupert can break from his work, he claims there are two restless and amorous spirits in his house, named Lance and Vicky, who like to have sex on the furniture, and Miles, a rotten brat of a nephew who wants to inherit his money. It's bound to be a long night of sex, and no one knows what the morning will bring.
