Authors with the most books->movies?
 

13th Warrior came on tv and said it was based on the Crichton book. I had forgotten he wrote that

in no order
13th Warrior/Eaters of the Dead
Congo
Andromeda Strain
Timeline
Jurrasic Park

Stephen King.

There is also an old top 10 here: http://www.epinions.com/content_1674485892

William Shakespeare.

What? That's not what you meant?

I'd be willing to bet that Danielle Steel has got even SK beat. Seems like I'm seeing commercials for tv movies of her crap all the time.

doh, didn't even think about King
seeing that shakespeare wrote plays I didn't count him at all, although I almost posted a little side discussion about him, so I guess I'll post that now
It's my contention that if shakespeare was born in the 20th century he would have been a movie writer with only a few plays in his early years or maybe from time to time to help pay the bills. his plays are on a grander scale (and I'm not saying this just because modern english teachers have a fetish towards him) than current plays which is why I think he'd go for movies in modern times and not stick to plays.

It would be more interesting to see a percentage. King and Steele have obviouisly written more, so it would seem more accurate.

How would one count King's short stories that were turned into movies?

Grisham's "Street Lawyer" was on TV? I totally missed that. Too bad my favorite, the Partner hasn't been touched yet.

Ian Fleming had all his James Bond novels and most of his stories made into movies. He also wrote Chitty Chitty Bang Bang.

I admit that for a lot of the movies, the only thing in common with the book is the title.

Ditto for Arthur Conan Doyle and the multitudinous televisual and cinematic adaptations of his few novels and many short stories.

I don't know the exact number off the top of my head but I'd guess that Graham Greene has had at least a dozen of his books made into films including: "The Quiet American", "Ministry of Fear", "This Gun for Hire", "Our Man in Havana", "Confidential Agent", and the old John Ford/Henry Fonda movie "The Fugitive".

Shakespeare would have totally gone for Hollywood. His plays are considered high literature now, but 400 years ago, they were entertainment for the masses.

Hemingway's got about 40 different TV and movie adaptations of his various novels and short stories. Faulkner's got about 20, and then another 20 movies or TV shows that he worked on as a writer, either doing original screenplays or adapting someone else's stories. Steinbeck's got about 30 versions of his stuff, although if you get rid of the various adaptations of Of Mice and Men and Grapes fo Wrath, it probably knocks out half his stuff.

Louis L'Amour must have a dozen or more.

Stephen King. Here's his list (includes movies in productiion and TV):

Charles Dickens has to be up there in adaptations too.
