There are always Tintin vcds or videotapes on ebay. I've been looking at them for a while, always toying with the idea, but never went for them.
There are a couple of Tintin movies that have been made, that I'd like to track down for the wife. ("Tintin in the Lake of Sharks" is one that comes to mind). There even was a non-cartoon Tintin movie made (in French), but I have yet to see anything more than a reference to that one.
Those 3 book sets are nice, even if they are smaller than the originals (which is what my wife prefers), but they leave out the first two Tintin books, which aren't easy to find (Tintin in the Land of the Soviets, Tintin in the Congo). They have been recently re-released in French, and the first one in English (not sure about Congo), but they have edited out some pages, so they miss some things from the original comic strip.
There are some good websites with all of this info (and more) out there, it's been a while since I visited them. One in particular that I remember (I have no idea where it is anymore) talks about parts that have been edited out of newer edition books. Quite interesting reading for true Tintin fans.
I did find (on Kazaa) some Tintin audio, apparently from a radio program. I never did listen to it, so I don't know what language it was, I think it was French, but I may be wrong. I can always put them back into Kazaa for the interested. 🙂
