I bet it is going to be like Hitch Hickers Guide, the film, where all the characters do not even look like the original and the entire plot line was ruined.
Ok, now I believe Regalsin is racist.
While the HG2tG wasn't perfect, it was pretty good IMO. The main issue I've heard people complain about was that they had Mos Def play Ford Prefect. This seems like a "change" in some people's minds because some people never consider an imaginary character as black unless you specifically say he is. By default, in the minds of some people, they are white (see: Jesus). In the books Ford's appearance is barely mentioned and even though HE'S A f*ckING ALIEN FROM OUTER SPACE they assume he's Caucasian.
My biggest problem with the movie was making Oolon CollUphid, who is only breifly mentioned on the first page of the book, into a large and rather gross subplot.
My favorite part was having Tim play Arthur.
