'The Help" is just the latest bestseller to be shoehorned into the multiplex. Most big-budget movies are adapted from other media, and books are a reliable resource. But few movies are adapted seamlessly.
Often the author forfeits the right to contribute to the project -- or visit the set. Vladimir Nabokov's very literary screenplay for his novel "Lolita" was gently tossed aside by fellow genius Stanley Kubrick.
At least half a dozen writers worked to whittle Margaret Mitchell's sprawling "Gone With the Wind" into a movie, including F. Scott Fitzgerald.
Fitzgerald's "The Great Gatsby" is being filmed for the third time -- in Australia, by risk-taker Baz Luhrmann.
Luhrmann tackled one of the most canonical works in Western literature for 1996's "Romeo + Juliet." The many movie adaptations of Shakespeare's plays, from "Forbidden Planet" to "A Midsummer Night's Sex Comedy," prove that timeless stories can be updated, but there is no guarantee that a great novel or play will be a great film. The movie versions of "To Kill a Mockingbird" and "One Flew Over the Cuckoo's Nest" took off, while "Rabbit, Run" and "All the Pretty Horses" stood still.
Which is better: the book or the movie?
"Alice in Wonderland," published by author Lewis Carroll (1865), filmed by director Tim Burton (2010): Carroll's book has inspired many versions, including cartoons and even a porn film, but Burton's gloomy, gothic abomination stripped all the wonder from Wonderland. And it may be the worst example of 3-D since "Andy Warhol's Frankenstein."
"Freakonomics," written by Steven D. Levitt and Stephen J. Dubner (2005); directed by Heidi Ewing, Alex Gibney, Seth Gordon, Rachel Grady, Eugene Jarecki and Morgan Spurlock (2010): Nonfiction books are a trendy new source for movies, such as "The Social Network" and the upcoming "Moneyball." This anthology about socioeconomic anomalies had several directors and covered subjects as diverse as sumo wrestling and the racial implications of people's first names. The result was more fuzzy than freaky.
