Remember: if we ever meet extraterrestrials, they may turn out to be weirder than anything we carbon-based meat units could ever imagine. I have no idea what kind of aliens are talking here, but I like to think that they're Blue Hooloovoos.
Speaking of which, John Malkovich will have a role in the upcoming HHGTTG film, as "Humma Kavula." There's no such character in the book, though; apparently the late Douglas Adams penned a screenplay which is significantly different from the book in many ways.
Why can't people just be happy with the excellent 80s TV series of the book? Does anyone really think that this movie can improve on things?
