A great way to compare this is to look at the HGTTG books, compare them to the BBC mini series which had so much of it line for line and compare THAT to the movie from the 2000's, which was adapted for American movie sensibilities.

Also similar is Discworld books, which are hugely reliant on puns and wit and asides and digressions and compare them to the several TV movies of them that were made for the BBC.
