10 Famous Actors You Completely Forgot Were In Doctor Who

David Morrissey

David Morrisey has achieved international renown for his turn as the Governor on The Walking Dead. Despite only appearing in 19 episodes from 2012-15, Morrisey was part of the zombie drama at the peak of its success and his terrific performance ensured that his character is still often called the greatest villain the show’s ever had.

On Doctor Who, however, Morrisey got to try his hand at lighter fare – though he played a role that appeared to be hugely important to the show’s mythology. In 2008’s Christmas special “The Next Doctor,” David Tennant’s Time Lord encountered a man in Victorian London who claimed to be a future version of him! However, it turned out that he was really just a confused human named Jackson Lake.

As he played a would-be Doctor on the series, Morrisey is another actor who has been frequently linked with taking the main role in the years since. While that’s probably not on the cards due to his busy career, he has said he would love to return to the show in some capacity.
