A new role for Sir Jimmy?

This year's Oxford Street Christmas illuminations come courtesy of Disney's promotions budget, puffing their new cinematic extravaganza: A Christmas Carol, starring Jim Carrey.

Now, nobody else seems to see it, but every time I pass by, the image on show strikes me not as Jim Carrey, but as the one, the only, goodness-gracious, as it 'appens boys & girls....Sir Jimmy Savile.

Guys, help me out here. Is it just me, imagining things again?

Or has Sir Jim taken to the rainy London skies?
And if it is him ...... what has he done with Jim Carrey?
