People who are interested will probably have seen the film by now. If they're very interested, they'll probably have read about how the film didn't do as well as the studio had hoped at the American box office. They might also have read that the film did very well in the rest of the world, but that despite that, the studio isn't likely to make the sequels.
I haven't got very much to add to that except to say that many things about the film were excellent, especially the performances. Of course Im disappointed that were not likely to see Dakota Blue Richards acting the rest of Lyra's story, and Nicole Kidman doing Mrs Coulter's final speech, and Sam Elliott holding out against the enemy forces at the pass in the mountains and a hundred other things; but there we are.
