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. 250px|right|A series 6 trailer prominently featuring Sheppard 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; several themed advertising campaigns such as "Top Eleven for the Eleventh Doctor"; and most BBCA continuity announcements related to Doctor Who. His voice was always used, for instance, to render the lines giving the time and day of an episode's broadcast. Frequently, as in the video at right, he was used to add narrative accents, as would be typical of an American theatrical movie trailer.

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, Warehouse 13 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.
