From 1986’s Deadly Friend, directed by Wes Craven:

Now, it should be noted that this scene was not in Craven’s initial cut of the film.  Craven envisioned Deadly Friend as being a melancholy love story about a teenage boy who brings his dead girlfriend back to life.  Elvira, the lady who loses her head, originally had a much less graphic death scene but Warner Bros. wants to take advantage of Craven’s reputation for being a horror director so they demanded a more extreme version and that’s what Craven delivered.

In my opinion, this scene is just ludicrous enough to work.  The studio’s demands were a bit silly so Craven supplied them with perhaps the silliest death scene that he ever directed.  That said, I do think Craven’s original version of Deadly Friend sounds like a nicer movie.
