Viktors Ritelis

Viktors Ritelis (born 10 December 1937) was the uncredited production assistant for the Doctor Who television stories The Crusade and The Daleks' Master Plan (with Michael Briant). The director of The Daleks's Master Plan, Douglas Camfield, apparently wanted Ritelis to receive co-director credit on the story. (About Time 1)

When William Russell refused to have ants craw up his arm while filming The Crusade, Ritelis was used as the hand double for Russell during filming. (DWM 259)
