Mark Sheppard joins Doctor Who Convention line-up

A new set of guests including Mark Sheppard have joined the line-up of the first ever Official Doctor Who Convention which will be taking place in Cardiff next month.

Sheppard was an instant hit with fans playing the role of Agent Canton Delaware III in the opening episodes of Series 6 The Impossible Astronaut and Day of the Moon, helping the Doctor to eliminate one of his creepiest foes – The Silence.

Sheppard said: "I grew up watching Doctor Who, and the fans are a huge part of what really makes the show so very special. I can't wait to come back to Cardiff for this unprecedented behind-the-scenes event - a unique chance for fans to meet the amazing people responsible for so much of the show we all love and get to experience their talent and creativity in a totally new way"
