Wilde plays upon the conventional images of how a ghost has been represented in popular imagination and literature to draw his portrait of the ghost. It was the stereotypical picture of the old manorial ghost in a suitably haunted house, playing on key elements from gothic and supernatural stories. The blood stain, the back-story of the ghost and usage of the tropes from this genre add to Wilde's object of stereotyping the ghost. In spite of the fact that the ghost had come to this state by murdering his wife, Wilde did not let the story become macabre or sinister. He maintained the humour by making the ghost an object of humour, the narrative offered by the ghost himself. The ghost was actually quite benevolent as is reflected by his treatment of Virginia. Also, he had been harassed and hassled more than the human beings in the story. As a ghost he is portrayed as ineffectual in scaring the human beings away, instead the human beings force him to beat a hasty retreat. The point of similarities between the film and the novel also rests on the wit and humour that is continuously evoked through funny situations in the film as a consequence of the novel. The film is a fantasy comedy made to appeal to children.
