Why do they lie so big?

I've read quite a few creationist/apologetic books in my days and I must say that there are some arguments that could be presented in a discussion, some things that could be brought up that would not suffer direct ridicule. Most of them can easily be solved but they could still be convincing to an ignorant or religious mind.

So why have the Expelled producers set out to lie so big, I wonder? Why do they claim such obvious falsehoods? Such as could be debunked even by none-scientific everyday journalists at the local newspaper?

Maybe they've read Adolf Hitler's Mein Kampf and found the passage about lying big as a useful propaganda tool. Hitler says that you should lie so big that no one would believe that you "could have the impudence to distort the truth so infamously".
