In reply to Alan:
I saw it last night.
The opening sequence was very good (both the dolphin song and the Earths demise), and I particuarly liked the Vogons. Call me old fashioned but I rather liked the prosthetic head favoured by the BBC TV Zaphod, otherwise a good choice. Trillian wasn't too bad either. Mos Def as Ford was pretty dull, he never quite managed to pull of the ethereal weirdness coupled with barking insanity of the Ford from the radio or books, and managed a sort of quiet blandness instead. Also Ford is supposed to be a consumate coward, not chasing after Vogons with a moist towel.
After all that there was still hope for the film to be excellent, but for Arthur.
No matter what he said or did it was just Tim from The Office, yeah okay he's an everyman sort of character, but just asking for tea every few minutes does not make him Arthur Dent. He singuarly failed to portray the middle-class, middle-England Telegraph-reading nervous-wreck that is Arthur Dent. And the love affair with Trillian WTF?
Yeah okay I'm comparing it too closely to the radio script and the books (which in themselves are different), but I felt that too many changes were made.
Still:
The Whale's inner voice? Inspired.
Slartibartfast? Genius
Magrathea? Brilliantly realised
Marvin? Alan Rickman was superbly miserable
The Cameos? Had me leaping from my seat and pointing at the screen, much to my partners lasting shame.
So yeah, it was okay, not bad. It might have been even better if I wasn't such a pathetic Hitchhikers fan-boy in the first place.
