With a League of Gentlemen twist:
Tubbs and Edward as Galadriel and Celeborn. Would eliminate the need for any Elven guards on Lothlorien, as everyone would be too scared to go near. "This is a local wood, for local people".
Papa Lazarou as Aragorn. As Arwen places her hand in his his true nature is revealed and he growls "oooh, you're my wife now", and then locks her up with his collection of other wives.
Hilary Briss as Gandalf, the grand meat butcher overlord, insidiously infecting the peoples of Middle Earth with the insatiable desire for 'special stuff'.
If you don't know to what I am referring then why not?
