13. Paul McGann (The Eighth Doctor, 1996)

Paul McGann was considered highly unremarkable in the 1996 TV movie "Doctor Who." That may explain why it took another nine years before BBC brought back the series. He was given a chance to prove himself in the role again in a 2013 mini-episode in which his decision to fight in the Time War gave us John Hurt's the War Doctor. For that, we owe him our thanks.
