The one problem I have with science fiction movies is that they often are trying to present a philosophical view of the world. In T3 it was predestination, Xmen pushed the religion of evolution, and The Matrix movies had too many to count. The Hitchhiker's Guide to the Galaxy is no exception.
The Guide pushes the world view of nihilism. Quickly put, this view believes that god does not exist, we have no purpose in life, and therefore nothing has meaning. Life thus is a cosmic joke, and we are on the receiving end.
Look at the link to: Exclusive Clip: "Whale"

It clearly shows the futility of life from the perspective of a nihilist.
Don't Panic! (And thank you Mr. Hagberg for your World View class.)

Thanks for the reminder
We had talked about the book before, and having not finished it, I wasn't sure what to think of the movie.
If sinful man says he doesn't know anything, then he "thinks" he is free from obligation. He knows there is a God, its written into his image. No amount of "intellectual sarcasm" can take that away.
Nihilism Ni"hil*ism, n. L. nihil nothing: cf. F. nihilisme. See Annihilate. 2. The doctrine that nothing can be known; scepticism as to all knowledge and all reality. 1913 WebsterA futile attempt to annihilate God, by attempting to annihilate knowledge. Sadly, many will be forced to bow to the Truth of that knowledge when its too late.
