I would love to see it too! I think the “Yellow M” movie stalled in pre-production last year, if not earlier, so it’s nice to think it’s going ahead.
They had announced a lot of shooting to take place round Museum Street and other central London locations, then they lost the funding, or something. I like to think they had picked up the finance again, but it isn’t showing as a coming film in Rufus Sewell’s biog on imdb.com, so I guess he’s off it?
I’ve got the two Comcat English language books (ugly, shrunken, things!), as well as an Editions Blake and Mortimer book of the Yellow “M”, which is the proper size, and has sketches for the cover at the back. I think I bought them in GOSH! Comics, in of all places, Museum Street!
The Yellow M lists five further books on the back cover: Secret of the Swordfish (I & II & III) and The Mystery of the Great Pyramid (I & II), but I have never seen these, and don’t know if they really exist in English, or are just a case of The Crab With the Golden Nippers.
The Catalan editions have on the back of The Time Trap: The Mystery of the Great Pyramid (no indication if it was to be one or two volumes); The Mystery of Atlantis; and The Yellow Mark.
Confusingly, volume two calls itself “Atlantis Mystery”, not The Mystery of Atlantis, and in addition to The Time Trap, lists: Secret of the Great Pyramid (now down as Parts I & II) and The Yellow Mark.
I keep my eyes peeled for any other volumes, but have never seen any. Nobody holds the rights to English on the books at the moment, or at least nobody is currently publishing:
but there is an e-mail address if anybody fancies getting in touch to take them up! ;-)
I agree with tybaltstone that there are problems with Jacobs storytelling, but the books are quite entertaining. I got the animated version of “Yellow M” a couple of years ago, and it is fun. Nelvana did the animation, and there were 26 episodes made in French and English, so I am surprised that some TV channel hasn’t picked up here (Channel Five, are you listening??).
