Here's the list:
The Time Traveler's Wife
Captain Corelli's Mandolin
The Bonfire of the Vanities
The Scarlet Letter
The League of Extraordinary Gentlemen
The Cat in the Hat
The Golden Compass
And honorable mention was given to:
The Da Vinci Code
All the King's Men
The Lovely Bones
The Hitchhiker's Guide to the Galaxy
And...in the comments, a number of people mentioned:
The Clan of the Cave Bear
The Lightning Thief
and many others.
I haven't read all of those books (although I've read many) and I haven't see all the movies. Furthermore, I'm not going to comment about which movies didn't live up to my expectations, which books were better, which movies were better or even which books I'd like to see made into movies. What I find most interesting is how strongly people feel about this topic. If you read the comments that accompany the article, people feel very strongly about which of their favorite stories fell flat (or worse) when brought to the big screen.
More importantly, I found reading the comments a great source of future reading material. Lots of books I've read, but also lots I haven't gotten around to. With people feeling so strongly about their choices, I'm planning to pick up a few of these books. I might even watch some of the movies I haven't seen, at least for comparison's sake.
Do you have any movies (or television shows) that disappointed once they were translated into another venue?
Have a great day!
