This short film recreates King John's death scene at the end of the play (imdb.com)

The opening scene is in Elsinore, where a ghost is seen by the sentinels keeping guard on the battlements of the castle. This is related to Hamlet by his friend Horatio, who describes the spirit as much resembling the late King of Denmark, his deceased father, whom his Uncle Claudius is suspected to have murdered in order that the latter might usurp his throne. Uncle Claudius also married the queen, the mother of Hamlet, within a month after.
