A star-studded supporting cast enhances the enjoyment of this four-episode Doctor Who episode, which first aired from September 29 to October 20, 1979. Arriving in modern-day Paris, the Doctor (Tom Baker) and Romana (Lalla Ward) join forces with a private eye named Duggan (Tom Chadbon). Their mission: to thwart the evil Count Scarlioni (Julian Glover), who plans to pilfer the Mona Lisa so as to raise funds for his Time Travel experiments. Confusing the issue is the fact that the Count already has in his possession six other Mona Lisas -- and all originals. Catherine Schell co-stars as Countess Scarlioni, while comic actors John Cleese and Eleanor Bron make cameo appearances as loony art dealers. City of Death was written by Douglas Adams and Graham Williams.
