(On Uncle Vernon from the Harry Potter movies) "Vernon distrusts Harry completely and is always concerned that he is going to do something strange at any moment. That is Vernon's biggest fear - he doesn't want anything strange happening that the neighbours might see."

If I had my way, all actors over 55 would be issued a 3-lb. wet salmon with which to slap the face of every young, beautiful, successful upstart. 'That's for being so lucky, you bastard!' I would shout. And then, hit them again, if you can.
