Viktors Ritelis
From Tardis Wiki, the free Doctor Who reference
Viktors Ritelis (born 10 December 1937) was production assistant for the Doctor Who stories The Crusade and The Daleks' Master Plan (with Michael Briant).
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)
