It is coming out this summer. Basically fans of the book will not recognize any of the story, at least from what has been released. He may be perfectly fine acting in it, but a big deal was made that he was pushing to get the picture done. He will share the blame in many a fans eye for blaspheming the book.
Ah....ok. Explains a lot. Kinda like “The Lord of the Rings” (although a huge majority of fans of Tolkein’s tomes loved the movies; gave Jackson a pass due to limited screen time, even spread across 3 movies) or “The Hunger Games” or countless other books-turned-into-movies. It’s VERY hard to please fans of the original books; almost impossible.
“The Hunt for Red October” was an exception....outstanding movie, very true to the book. There are others, but I have never heard of the book “World War Z” so I won’t be “upset” that the movie strays....but I can certainly understand why diehard fans would be.
