Admittedly there is a logical point in the book where it could be broken into two films, basically when the unicorn becomes human. However, it's not THAT long a book; so a single-volume adaptation still makes sense. I could see a two-hour film being made from the source material... The animated film was less than 90 minutes long and remarkably well scripted for what it covered.
What I mean by additional stuff are elements such as Hagsgate (the town above which Haggard's castle sits and where Lir came from) and its prophecy, the four men-at-arms (mentioned once in the film but not seen), and the various concepts of immortality explored in the book but not the film - the unicorn is immortal, but there was a whole character piece for Schmendrick on how he was older than he appeared, and ditto for Molly Grue's mortality and yearning for the young girl she was and sees in herself by traveling with the gang.
I only hope that whoever would step up to do this, would go for a fully CG unicorn and not a horse with a prop horn, as the aforementioned studio was gunning to do. One thing the film captured perfectly was the non-equine look of the unicorn, and doing something similar (would they even have the rights to the original character design?) would be absolutely required IMO. I don't see huge names attached to a script like this and won't bother speculating - but the book holds a special place in untold millions of people, and I'm sure many names in the biz will have read it and would love a chance to adapt it.
And no musical numbers, please.
