I finally got to see The Hitchhiker's Guide to the Galaxy last night. Woot! There were definitely changes from the books, but not a single one of them bothered me. It felt like they had captured the tone and the spirit just right.
There wasn't a single performance that stuck out in a bad way, and many that tickled me. Stephen Fry was just the voice for the Guide, just the voice indeed. So quintessentially, unflappably British, just like his Jeeves. Martin Freeman perfectly captured the frustration and bewilderment of Arthur Dent. Mos Def had the casual charisma necessary for Ford Prefect. Zaphod always has gotten on my nerves, but that is kind of his function, so Sam Rockwell had it just right (did I detect a note of Dubya in that performance?) The fabulously named Zooey Deschanel played a sweeter Trillian than I was expecting, and gave a semi-reprise of a scene in Elf. And, of course, Alan Rickman voicing the perpetually depressed Marvin had me in stitches.
If you have not yet seen it, be sure to stay through the credits, least you miss an extra treat.
