Before watching this I had not heard of David Tennant, although he is a household name in England for playing Doctor Who.
Now, having watched this I must say I am hugely impressed. He does not act Hamlet. He is Hamlet. In fact he has a certain quirkiness that lends itself to Hamlet's feigned madness. Even though we know he is putting on an antic disposition, because he says so, yet we don't know if he has crossed the line from feigned madness to real madness. We do have good reason to wonder given the extremity of what happens.
If you're like me, as you watch this version the fresh insights come dripping fast. What struck me particularly were the parallels between Hamlet, Ophelia, and Laertes, all of whom have experienced the same event, the murder of the father. Hamlet responds by pretending madness but being passive and indecisive, considering suicide as in being and non being, Ophelia responds with real madness and actual suicide, and Laertes responds in a more active way by decisively challenging Hamlet to avenge the death of both his father and his sister.
The queen falls under the witchcraft and wits of Claudius gifts, with witchcraft of his wit, with traitorous gifts,-- O wicked wit and gifts, that have the power to seduce our seeming virtuous queen. Apparently, this is a rather pointed reference to Archbishop W(h)itgift, who with his Machiavellian tactics seduced the ear of Queen Elizabeth. In any event this reference was removed from the original 1603 quarto, reappearing in the 1604 quarto, after Whitgift, and Elizabeth's death.
I loved this modernised version of Hamlet, with the original language, with the closed circuit tv's, reinforcing the idea that Hamlet was being constantly watchied by double dealing courtiers. Compared to Zeffirelli's version of Hamlet where Polonius is a wise old man, here he is a hard to pin down courtier, who carefully contrives to be non committal in his answers.
All the elements of the writer seem to work. I liked the speak the speech scene, Act 2, Scene2, where they spent 70 lines discussing the killing of Priam from the obscure play Dido by Marlowe. I loved the wit of the gravedigger scene. There is so much to love about this production. Ophelia goes impressively mad, I don't think I have seen this as well done before.
Patrick Stewart does a great job playing both Claudius, and the ghost of the late King Hamlet.
I highly recommend you do check out this version. Along with Zeffirrelli's version of Hamlet starring Mel Gibson, this is my favorite.
I think you will love it, and I hope this was helpful.
