So! Is it Christopher Walken, or Christopher Plummer? And what does “Walken in a Winter a Wonderland” have to do with Christopher Plummer? How do you spell abstruse?
The answer is Christopher Plummer. Christopher Walken was the hint to first name, and the occupation of the second clue was the hint to his stage last name. The camouflage was a simple distraction!
And this is the joke for 'Walken in a winter wonderland'...a play on the Christmas song.
