Feth Greenwood (Karl Greenwood) was educated in St. Albans, Hertfordshire. He played in bands on bass, guitar and violin before performing more physical roles in fireshows, stiltwalking and trapeze acts on the festival and club scene in Europe. During this time he also pursued a career in timber extraction using horses. In 2004 Karl combined his equine skills with his passion for performance to create The Stampede Stunt Company - a horse stunt team performing live shows of jousting and trick riding which still performs. His breakthrough into filming came in 2004 with the new series of Dr. Who (the David Tennant era) where, already well experienced in limited vision in his role as a knight, he became a skin worker for the monsters of Dr. Who. This was followed by his first indoor arena tour of Dr. Who Live in 2009. A short promotional video for a novel was the first lead role in film, soon followed by the role of Eldred in 2011 feature film Dragon Crusaders. He continues to ride his horses for film and TV, and for live shows.
