In addition to these ten official actors, several other actors have played the Doctor in canon and non-canon productions. For the anniversary special The Five Doctors, Richard Hurdnall assumed the role of the first Doctor, replacing the deceased Hartnell. An evil incarnation of the Doctor from the future played by Michael Jayston caused problems in the epic serial "Trial Of A Time Lord". Richard E. Grant played an alternate Ninth Doctor in the animated webcast "Scream Of The Shalka". Actors Rowan Atkinson (Mr. Bean) Richard E. Grant again, Jim Broadbent (Moulin Rouge) Hugh Grant and Joanna Lumley (Absolutely Fabolous) also played Doctors in the charity spoof "Curse OF Fatal Death". Peter Cushing (Horror veteran and Tarkin in "Star Wars") also played the theatrical incarnation of the Doctor in "Doctor Who and the Daleks" and "Daleks-invasion Earth 2150 A.D" which were films loosely based on the show. A series of audio dramas, produced by Big Finish, also feature actors such as David Warner, Arabella Weir and Derek Jacobi play the Doctor.
