Doctor Who: 5 Men Who Were Almost The Doctor
But It Was Almost: If the only thing you know about Rowan Atkinson is Mr. Bean then I pity you for having never seen Black Adder. It's on Netflix streaming right now. Go watch it. I'll wait.
In case you didn't have time to go watch it, I'll give you the breakdown. Atkinson is a tremendous physical comedian, yes, but he's also capable of the driest, most sarcastic wit since Oscar Wilde. Not to mention capable of a tremendous darkness rivaling McCoy's own. It's a toss-up whether Atkinson would have been able to turn the tide of the clownish approach set out by Nathan-Turner as McCoy did, but if he had he probably would have gone down in the show's history the greatest Doctor of all.
