Pal's version is...while clos-er than the remake, it's already pretty close.
George Pal keeps the idle-vs-working evolution, but throws in an anti-war subplot about WWIII being one of the great triggers of division (the Eloi are still summoned to the underground tunnels by sirens that sound oddly like air-raids), which probably didn't occur to HG when he was writing the book, but feels like it's straight out of it.
Especially when you watch it right next to HG's own Blitz-era script for "Things to Come", where he thought WWII would wipe out civilization.
I've always thought that perhaps Wells would have liked the Pal film and it's changes. Apparently, as he got older he thought of his original novel as silly and out of date. We'll never know, but I always thought he'd have approved of the film.
