This does exist in printed form, I've seen one in a shop but I won't say where. It was very expensive. I did not buy it.
There’s no doubt that this and other books exist in printed form, and that people selling them will pretty much charge what they can get away with; this is why Rodier withdrew from the whole area, as there was rampant profiteering by others.
It doesn’t make what he did any more legal, but it shows that less scrupulous people will download these things, print them off and sell them.
Herge Studios drew up a comic version of Tintin and the Lake of Sharks that didn't include stills from the animated movie but it was never released to the public.
The book which we have isn’t really made of stills from the movie, as such, as has been discussed previously
The Studios produced a black and white newspaper strip version of the film, with simple backgrounds. This hasn’t been collected as an official album, in this simple version.
However in the colour book characters are drawn exactly
as they appear in the newspaper strip, but placed over backgrounds taken from the movie, so any drawn decor is not present.
The two versions follow frame-for-frame exactly the the same character art, and where there is an addition (meaning items such as sweat beads round heads to show anxiety, which are not shown in the film) in one, it can be found in the other.
What we don’t know is how and in what order the art was created; it could be entirely possible that the coloured art for the book was actually created first, as it would have allowed Studio artists to draw the simple black and white art from the more complicated colour backgrounds, which were already in existence and of course would have given them the necessary perspectives for their drawings.
I can see that the enterprise might have consisted of making a paste-up version using backgrounds and cel-animation drawings, to dummy up an album to length; this then allowed the Studio to copy the figures, add the hand drawn detailing that the characters had in other books (e.g. the sweat beads). Once this had been done, simplified backgrounds would be taken for the newspaper version, and the figures laid on this; colour versions would also have been prepared then laid into the existing backgrounds. Two versions with a common master original source.
But I don’t think there really is yet another, unseen, version of Lake of Sharks
, at least not one which varies to any great extent from what we have; there may be a straight, flat colour version of the strip, but I can’t see there being a big difference, other than that, and even that seems unlikely.
