Yep - it's out..... I really enjoyed it too.... Zaphod was great. When I pictured him in my head while reading he was egotistical but really ugly - with the two-head thing going on. I like the way he was in the movie... like a surfer rock star Dubya!
OH, and Alan Rickman was PERFECT as Marvin...I about had a cow in laughing at him. I had to watch it a second time to decide if I liked the girl who played Trillian, and the man who played Ford Prefect reminded me a lot of Danny John-Jules, who played Cat in Red Dwarf.
