Took Joseph, my mum and Tony to see this when it opened (last week?) at the Freemans Park Odeon.
Really wanted J to see it since I'd loved the TV series and books as a kid. Subsequently it's very hard for me to relate to the film in terms other than the horribly unfair ones of my childhood idealizations of the TV cast. Marvin in particular (who makes an appearance in the queue on the Vogons planet) was my absolute favorite character - the fact that he was poorly designed, lumbering and ugly added insult to injury as far as his massive braininess was concerned - and so was perfect. The new Marvin is much better designed - he can run for instance - but his large head annoyed me.
All the TV actors seemed just right for their parts - with the absolute exception of the old Trillian who seemed to have been cast on the basis of how shrill and completely annoying she was. Zooey Deschanel by contrast was really good in the role, although her current typecasting as 'beautiful girl who's quirky enough for the audience to consider her falling for the significantly less attractive male lead an almost realistic proposition' (see Elf for another example) needs addressing.
Mos Def did a good job with Prefect, but there wasn't enough edge to mark out the boundaries between eternal space student and intergalactic hippy. Bill Nighy's Slartibartfast had similarly undergone a horrible transformation from grumpy world builder to self effacing project manager.
There were funny parts, but I didn't come out of the film with that rush you get from seeing something really exciting. Joseph came out singing the Pythonesque theme tune and certain who his favorite character was: Marvin.
