The Avenging Conscience or Thou Shalt Not Kill 1914 is a drama film directed by D. W. Griffith. The film is based on the Edgar Allan Poe short story The TellTale Heart and the poem Annabel Lee.
The young mans torment continues, this time caused by guilt over murdering his uncle, and he becomes sensitive to slight noises, like the tapping of a shoe or the crying of a bird. The ghost of his uncle begins appearing to him and, as he gradually loses his grip on reality, the police figure out what he has done and chase him down. In the ending sequence, we learn that the experience was all a dream and that his uncle is really alive.
