Take this one for example, a perfect example of no time loss to make a much better joke. The Whale, falling to earth. The last thing he says is (in the book "I wonder if it will be friends with me". And that replace it with "Hello, Ground!". Why? Could that extra 2 seconds destroy the movie and make it too long? This is a perfect example of murdered adam's monologue. THIS is why we are ticked off, not because things are 'exact' but because they Americanized Wonderful British humour that can be grasped by the average american. (Note, Im an american). On anoher note, they could of just cut out some non-important parts of the story, shortened various sections, removed non-key dialouge and made a 2 hour movie out of the book WITHOUT editing anything. Oh well, thats Hollywood for you.
