Spot Duncan...

John Sessions told Duncan he looked like Kenneth Branagh, you know.

Sideshow Bob's brother, Cecil. Kind of a cheat, since he is played by David Hyde Pierce.

Niles from Frasier (David Hyde Pierce)

Peter Davison. Not only played the Doctor, but in addition managed to attract Joanna Kanska in A Very Peculiar Practice, thus also attracting Duncan's lifelong envy.

Elton John, looking rough.

Mark Gatiss, also playing the Doctor. I sense a theme.

Agatha Christie's HICKSON.

Ron Howard, back in the days when he had hair. Duncan's hair, in fact.

Charles Kennedy (is the one on the left). The fox looks quite like Duncan too, though. Boom Boom!

David McCallum. "Sapphire! Take Time Back!"

Persuasive Roger Moore.

Martin Chambers, the Pretenders' drummer.

Camp witch Anne Robinson.

Useless Thundercat sidekick Snarf.

Anne Widdecombe, looking ravishing.

Intelligent ape Dr Zaius.

Bill Nighy. He was very good in State of Play. Less so in Shaun of the Dead.

The man himself -- or is it?
