Spike and Suzy
Video games and animated and live action movies have been made for popular series like "XIII", "Tintin", "Spirou et Fantasio", "Spike and Suzy" and "Lucky Luke", and the long-running Hanna-Barbera series of "The Smurfs" became a worldwide success with massive merchandising, and the success continues as evidenced by the ratings animated cartoons based on the adventures of "Tintin" and "Lucky Luke" had in Germany and Canada in 2005 and 2006. But also more mature graphic novels like "The Wedding Party" by Hermann Huppen and Jean Van Hamme have been turned into movies.
