There are some movies about Tintin. The first is the Tintin TV series. It has 22 episodes so most of the comics adventures were filmed. Those episodes were later sold. The titles that were not filmed are: Tintin in Russia Tintin in Kongo, Tintin and Alph-Art. I understand that Tintin in Russia and Tintin and Alph-art could not be filmed but why nobody filmed Tintin in Kongo? I don't know. Anyway there is also a long film made by Steven Spieldzberg called "The adventures of Tintin- The secret of the Unicorn". Now there is only the 1st part but the second one will be done in 2015.
