While I was in Texas I went to the movies with DeboHobo to see The Curious Case of Benjamin Button. I'm not to sure how long the movie is, but I would guess over ninety minutes. The whole time the movie was exciting and it kept my interest. The outstanding thing for me about this movie is the makeup for the aged Brad Pitt. To my surprise in the credits I saw the movie was based on a short story written by F. Scott Fitzgerald.
Because I am an avid reader, I went to my local library and checked out Six Tales of the Jazz Age by F. Scott Fitzgerald. Included in those tales is The Curious Case of Benjamin Button. The short story is twenty-three pages long. Well, I read the tale last night and all I can say is the screenwriter definitely used a writer's license. We all know most movies are not the same as the original story, and some come fairly close, but this was quite a leap from the book.
The bottom line is both the movie and the short story are interesting and I would recommend both. The order you choose to partake is up to you, but for this one I would say movie first and than the short story.
