Tim Barlow (born 1936 as Michael John Leigh Barlow) played Tyssan in Destiny of the Daleks. He was profoundly deaf during the time of filming, the result of an incident with a rifle during his service in the Army; his deafness was thought to be permanent. However, in 2008, he received a cochlear implant, allowing him to hear again.
He has also appeared in films such as The Tall Guy with Jeff Goldblum (ironically, playing a blind man), and Hot Fuzz with Simon Pegg. Barlow has written and performed in autobiographical one-man shows such as My Army, about his experience in the military in the 1960s.
His experience with the cochlear implant was the subject of a BBC radio program, Earfull - From Silence into Sound.
