Even Phineas Fogg, in Around the World in 80 Days, doesn't alter his fundamental nature. He gains a wife by rescuing one.
Film versions tend to give Fogg a moment of epiphany or an alteration in goals. However, even film versions of Around the World tend to be mostly visual extravaganzas that focus on location, location, location.
One exception is not from Verne but about Verne: Doc and Clara Clayton in Back to the Future III.Doc and Clara are the original geeks or otaku, the original Dungeons & Dragons masters, the original cosplay, anime, manga, Lord of the Rings fans on their way to the next convention. Their romance is adorable since it involves that delighted recognition between the two that they share an interest...
A love of Verne.
