Number 1. Noddy Holder

Imagine seeing that sticking its head out of the TARDIS and bellowing “IT’S CHRIST-MAAAAAAAAS”. Terrifying and entertaining in equal measure.

Number 2. James Caan

“The only thing you can assume about a broken-down old man… is that he’s a survivor” - James Caan in Way of the Gun.

3. Brian Blessed

A loud legend. I’m somewhat biased here as I’d like to see Brian Blessed in everything and was only stopped from inviting him to my wedding when my wife vetoed the idea as we’d never met him.

4. David Attenborough

What a legend - and an atheist too

5. Rodney Dangerfield

Rodney died in 2004 so it’d be a short incarnation as The Doctor. I guess he’d just regnerate, look a bit pop eyed, then collapse and regenerate into a more viable candidate (see above).
