After Bernard Cribbins was spotted on set filming the last of the Doctor Who specials earlier this week, today saw the return of another familiar face, John Simm.

The actor, who played The Master in three episodes of Series 3 of the hit sci~fi show, was seen sporting a newly dyed blonde hairstyle on the grounds of Tredegar House. With Cribbins and Simm now in the bag, all eyes turn to next week when filming returns to Donna Noble's home and a possible appearance from Catherine Tate. She and David Tennant are presenting a BBC Radio 2 show on Saturday 11th from 10am until 1pm.

The last of the specials are due to be broadcast over the Christmas period with the finale, featuring Tennant's regeneration into Matt Smith, airing on New Year's Day. Russell T Davies recently revealed that the second of this year's specials will be broadcast before this period, shortening the gap for Who fans.

Planet of the Dead hits the small screen in the UK on Saturday 11th April on BBC One, 6.45pm with a simulcast on BBC HD.
