He had a regular role as Kai opposite Oliver Tobias's King Arthur on the aforementioned "Arthur of the Britons" during the early 1970s. He became known to a wider cinema audience for his menacing turn as the villainous (and non-speaking) Belgian henchman, Emile Leopold Locque, in the 1981 James Bond film, "For Your Eyes Only". Gothard was actually the one who suggested Locque's signature octagonal glasses in an effort to make the character more menacing. His later appearances included supporting roles in Tobe Hooper's 1985 science-fiction horror extravaganza, "Lifeforce", and as George Lusk in the 1988 TV movie, "Jack the Ripper", with Michael Caine. He appeared with Dean Stockwell and Shirley Knight in a Hammer House of Mystery and Suspense (a.k.a. Fox Mystery Theatre) episode, The Sweet Scent of Death.
