Matt smith (11th doc) in The pyramid at the end of the world...

Eccleston in The Doctor's Daughter.

The Eighth Doctor in The Day of the Doctor.

Eccleston in any episode of New Who.

Tom Baker in "Mummy On The Orient Express".

Or maybe David Tennant.

(Don't yell at me)

I think it would have been interesting to see 10 in Heaven Sent

Not yelling.

I agree.

Tennant is a great actor.

His Hamlet is praised.
