Perry Brahan

 was the visual effects designer on The Happiness Patrol and Silver Nemesis. His earliest credited work seems to have been on the final episode of Douglas Adams' televised version of Hitchhiker's Guide, where he was a visual effects assistant. He then worked on several shows in the 1980s prior to coming to Doctor Who. Amongst these was a Peter Grimwade-directed episode of All Creatures Great and Small, featuring Peter Davison and Lynda Bellingham.

Most of his career, though, came after working on Doctor Who. From Nemesis, he immediately went to the 1988 French and Saunders Christmas special. He then worked on Keeping Up Appearances with Clive Swift, as well as a number of other comedy programmes. By the 2000s, he was exclusively credited as having provided various special effects services, as the industry was beginning recognize Brahan's craft as "special", rather than "visual", effects. He also shifted away from series work, and tended to be involved more with tele-movies. In 2002 he was nominated for a Royal Television Society award for his work on the tele-film, Night Flight. Another of his 21st century jobs, 2007's Stuart: A Life Backwards, starring Benedict Cumberbatch, was also critically well received, though for acting rather than visual effects.
