I´ve allways loved Tintin and now my son does it too, and even more than me. Lindberg, as a swede are you familiar with the tape/LP-versions of the Tintin books? I get to listen to them more or less every day and it´s been so for a few years now... thankfully they´re really good, but we both know almost all dialoge by heart to most of the tapes by now... I think my favorite adventure is the one in Tibet with the Yeti.
The old animated tv-series are quite fun (Belvista i believe the company that made them were called), but to be honest not very well done and also not to close to the original books. I found copies recorded of swedish tv from the early 80s, my youth, and it´s 8 minutes episodes with extensive prologue and credits, they showed it on tv here once a week and i remember how important it was to turn on the tube at the right minute because the show was so short...
The two live action films are ok, but it´s incredible how much the actors resembles the cartoon carachters, got to be seen to be believed!
There also was two animated featurefilms made in 70s/early 80s, i remember going to the cinema as a kid to watch them, the first one Temple of the Sun has some musical numbers in it that i didn´t like (but the voice of Tintin was over here done by a guy who now is one of Swedens biggest sportscommentators) and the second Sharklake (freely translated) wasn´t based on an Hergé book and a bit dissapointing.
