Expelliwhozis

I was thinking the other day that for the next Doctor Who, they should get Daniel Radcliffe.  He's British, he's already known for wearing a set of distinctive unusual clothing which includes a long scarf... and he's famous for waving around a sonic screwdriver wand to unlock things and to disarm opponents and to do other magical stuff.  (The sonic screwdriver seems even more magical than the wand — with the wand, one has to specify the effect one is looking for, whereas the screwdriver seems to be just point-and-click.)

"EX-TER-MI —" "Expelliarmus!"  And the Dalek's gun-arm goes flying across the room...
