<Li> Jared Leto as Nemo Nobody , both 34 - and 118 - year - old . Nemo is a Latin word meaning `` nobody '' . The name Nemo alludes to Captain Nemo , the main character of Jules Verne 's novel Twenty Thousand Leagues Under the Sea . It is the false name that Odysseus in Homer 's poem Odyssey gives to the cyclops Polyphemus , to deceive him and save his own life . Van Dormael said that Leto was chosen because he is `` an actor who could transform himself , as much physically as vocally , rhythmically , his breathing . '' Leto described his role saying , `` Mr. Nobody is everyone and no one all at the same time , an illusion , the product of his own dreams . He 's love , he 's hope , he 's fear , he 's life and he 's death . This is without doubt the most complex character I 've ever played . It was a challenge to keep all these lives concentrated into one character for the duration of the filming without losing myself . But we had outlines and things that helped me to keep track of where we were . '' Actor Toby Regbo portrays Nemo at fifteen and Thomas Byrne Nemo at nine . </Li>
