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 BBCA's "voice of Doctor Who" during the original run of the series. During 2011, he lent his voice to the documentary, Doctor Who: Rewind; the behind-the-scenes series, Doctor Who Insider; and most BBCA 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.
