Captain Nemo and the Underwater City is a 1969 British film, featuring the character Captain Nemo and some of the settings of Jules Verne's novel Twenty Thousand Leagues Under the Sea. It was written by Pip and Jane Baker and stars Robert Ryan as Nemo. It is considered a follow-up film to the 1954 film 20,000 Leagues Under the Sea and 1961's Mysterious Island. From the plot however, this is not clear. Whilst in Verne's book the events of '20,000 Leagues' are stated as taking place in or around 1866, and the events on the 'Mysterious Island' as later still, characters in the 'Underwater City' refer to the War between the States as currently ongoing, which places it before '20,000 Leagues' by as much as five years.
