Mark Sheppard

Mark Sheppard portrayed a young version of Canton Delaware in the opening two parter of series 6 of Doctor Who, The Impossible Astronaut and Day of the Moon. His father, William Morgan Sheppard, portrayed an older version of the character in the opening episode.

Sheppard's involvement with series 6 was greater in the United States. He was effectively the "voice of Doctor Who" during the original run of the series, lending his voice to the documentary, Doctor Who: Rewind, the behind-the-scenes series, Doctor Who Insider, and most advertisements and continuity announcements related to Doctor Who.

Sheppard is also well known for the amount of tele-fantasy series he has appeared in, including The X-Files, Star Trek:Voyager, Firefly, Battlestar Galactica, Dollhouse and Supernatural amongst others. He also had a recurring role in The Middleman, a Torchwood-esque action series which featured many references to the Doctor Who franchise.
