Sketch of Hugh Despenser (Maybe ;-) )

OK, I'm no artist, but I do like to use images to bring my written characters to life.

Here is my first picture of Hugh Despenser the younger (Yes, there will be more I'm afraid!). The way I 'see' characters is by having an initial image of them in my head and then 'casting' a current actor or actress to play them (as if it were a film). Can you guess the actor I have cast for Hugh, based on the picture (a clue - he's British and no stranger to sword-play)? All correct answers win a virtual trip of the imagination in a century of their choice!
