John Brace
John Brace was the visual effects designer for the Doctor Who television stories Full Circle, The Five Doctors and Revelation of the Daleks. He had earlier been an uncredited visual effects assistant on The Seeds of Doom (INFO: The Seeds of Doom) and The Talons of Weng-Chiang. (INFO: The Talons of Weng-Chiang)
His career seems to have started in 1979 with work on Terry and June, starring June Whitfield. He then provided visual effects for the original pilot of Richard Curtis and Rowan Atkinson's The Black Adder, but was replaced by Chris Lawson once it went to series. He next worked on The Young Ones and the 1987 BAFTA winner for "Best Drama Series", The Life and Loves of a She-Devil. Brace's work after 1987's Gaudy Night with Caroline John — if any — is not well documented.
