8 big book-to-movie adaptation changes we loved (plus 3 we hated)

It’s not uncommon for directors to make some changes when bringing books to the big screen. But not all tweaks are created equal.

With World War Z opening this weekend, and essentially related to Max Brooks’ novel about the oral history of the zombie war in name only, we’ve decided to pull together a few of our favorite (and least favorite) ways that sci-fi movies have been changed over the years.

From dropping heavy-handed political messages to throwing away the ending, there have been a lot of nips and tucks made over the years to classic sci-fi stories. Check out our list below and let us know about some of your favorite (and least favorite) changes.

Obviously, some spoilers ahead!
