Sadly, I missed out on the July 20 Tintin Festival in Brussels last month, but I would have loved to have been there to celebrate the history of one of the most wonderful creations in the history of graphic narrative.
If you've never read any of Georges "Herge" Remy's comic adventures, they're readily available in any major chain book store or comics shop worth its salt, chronicling the tales of boy reporter Tintin, his faithful hound Snowy and, after the early volumes, his profane alcoholic cohort Captain Haddock. I started reading these stories around age 7, and thankfully my parents weren't paying close enough attention to note the books' portrayals of drug smuggling, drunken binges and the occasional racial stereotype in the earlier books from the '30s and '40s.
Remy's attention to graphic detail, outlandish supporting characters and a wide swath of international intrigue made them fascinating reading at an early age, and they hold up pretty well decades later. Supposedly Spielberg has the film rights, and has made some noise about actually producing a Tintin feature, although there were French language live-action films produced in the '60s--and more obscurely, a stop motion animation version of The Crab With the Golden Claws in 1941--not to mention two separate animated TV series of varying degrees of faithfulness. There's also Philippe de Broca's That Man From Rio, an entertaining adventure starring Belmondo that just happens to be a direct swipe from the Tintin adventure The Broken Ear, and while not official Tintin, is pretty entertaining in its own right (and, bringing things full circle, a heavy influence on Indiana Jones).
Don't be a bashi-bazouk, get some Tintin in your library tout suite.
