* ActingForTwo: Due to the briefness of the first part and the fact that they were supposed to be brothers anyway, some productions have the Ghost and Claudius being played by the same actor. Some see Hamlet's "Look here upon this picture"-speech as proof that this was Shakespeare's intentions and him [[LampshadeHanging lampshading]] it. Note that the guards hang around talking at the end of act 1 scene 1 just long enough for the actor playing The Ghost to jump into his Claudius costume for the start of scene 2.
** The Royal National Theatre production with Simon Russell Beale had the actor playing Polonius doubling as the First Gravedigger, accompanied by some LeaningOnTheFourthWall: appropriately enough, given that Polonius was dead, the actor arose from a coffin to play the Gravedigger.
* BeamMeUpScotty: One of the most common misquotations ever; the AlasPoorYorick line goes "I Knew Him, Horatio.", ''not'' "I Knew Him Well."
* HeyItsThatGuy:
** Why on Earth would [[Film/HarryPotter Professor Lockhart]] be trying to kill [[Series/DoctorWho the Master]]?
** Why would [[Series/DoctorWho the Tenth Doctor]] be trying to kill [[Series/StarTrekTheNextGeneration Captain Picard]]? It's especially creepy because Creator/DavidTennant's "mad" Hamlet is unnervingly like his goofy Doctor.
** [[Literature/{{Dune}} Paul Atreides]] gets to be on the receiving end of a son's vengeance for his father's death.
