Top choices:
Richard Coyle – It’s a shame he and Steven Moffat parted on such bad terms. I think he’d have made an excellent Doctor; quirky, yet with real passion.
Patterson Joseph – Would have been brilliant. A strong traditional choice with a nice amount of gravitas.
Jack Davenport – I think he’d have done fine but I’d never be able to take him seriously in the role.
Hugh Jackman – Action movie Doctor wouldn’t be the end of the world.
Bill Nighy – Creepy wise old man portrayal but with a good sense of humor about him. Kind of a more powerful, more self-assured Slartibartfast.
Lenny Henry – A more comic choice, a good way to transition from the lightheartedness of the Tenant years.
