Colin Teague
From Tardis Wiki, the free Doctor Who reference
Colin Teague has directed several Doctor Who universe stories. He was the first of very few directors to have worked on all of the first three BBC Wales series.
He became widely known amongst BBC Wales personnel as "Tumblin' Teague", following an incident during the filming of The Sound of Drums in which he fell and required brief hospitalisation. David Tennant revealed the nickname in commentaries for series 3 episodes.
Since working on Who, he has directed episodes of Being Human, for which he was nominated for a BAFTA.
