Mark Sheppard in Doctor Who

Fans hoping to see Mark Sheppard at Valleycon this past weekend were disappointed to learn that the actor had to cancel at the last minute. The reason: he has landed a rather juicy role on the sixth series of Doctor Who and they needed him there right away. Sheppard is of course a veteran of genre TV having appeared in such shows as Firefly, Dollhouse, Battlestar Galactica and Chuck, to name just a few.

No word yet as to what character he will be portraying or what the episode is about, but no doubt he will make this role every bit as memorable as his others.
