This document summarizes and compares Jules Verne's classic novel 20,000 Leagues Under the Sea with a graphic novel adaptation. It outlines the main characters - Professor Pierre Aronnax, his assistant Conseil, and harpooner Ned Land. It describes how they are taken prisoner aboard Captain Nemo's futuristic submarine the Nautilus and embark on underwater adventures, but eventually realize Nemo is mad and escape under cover of moonlight. While staying mostly faithful, the graphic novel adaptation contains less descriptive detail and fewer small conflicts than the original novel.
