* 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."
** Another is "The Queen doth protest too much" or "Methinks the Queen doth protest too much". The actual line is "The lady doth protest too much, methinks."
** Also, when Hamlet is referenced in media or other fiction, it usually combines his "To be or not to be" with the image of him holding Yorick's skull, which is a different scene altogether.
* DawsonCasting: ''Magazine/{{MAD}}'' joked that in the 1990 film version, Hamlet and Gertrude seem to be the same age. While not quite the case, it ''is'' bizarre to have Creator/MelGibson - 34 at the time of production - play the son of then-43-year-old Glenn Close! Hence the trope PlayingGertrude.
* ExecutiveMeddling: Kenneth Branagh was only able to get financing under two conditions: a) An AllStarCast and b) and shorter cut for wider release.

* WordOfStPaul: The text of much of the notoriously garbled First Quarto of Hamlet is widely believed to have been reconstructed from memory by whoever played Marcellus in an early production, because all the scenes with Marcellus in them are closer to their counterparts in later editions, whereas whenever Marcellus is offstage the text starts to read like a best guess by someone who's witnessed several productions but has never bothered to memorise the whole thing. The 'mousetrap' scenes in the First Quarto are also very much as they are in later editions, suggesting that the actor doubled up (highly common in Renaissance theatre) and was in those scenes too.
