Up In the Air: Which do you like better? The book or the movie?

I was cruising around on my Nook - I actually live so close to Barnes and Noble now, that I can walk there in ten minutes and settle in for a free hour of reading on my Nook - and discovered (or perhaps re-discovered and I've just forgotten) that the gorgeously poignant Up in the Air film starring George Clooney and directed by Jason Reitman started out as a novel by Walter Kirn. If I had known that back when the movie first came out I think I would have read it before seeing the film. But now, just like with The Descendants; I won't be able to get Clooney out of my head. Not such a bad thing really but I wonder who I would have pictured as Ryan - or how I would have pictured him - had I read it first myself. Interesting in the script, he's not described at all. he is everyman. The first 17 pages of the book are the same.

I just finished reading the script over at the internet movie script database (imsdb.com) last week and I think it could be fun to see how the book, compares to both the finished film and the script.
Which is really interesting when all three differ from each other.
On the other hand I'm dying to get back to The Corrections, the Jonathan Franzen book that was slated for the screen too. Once upon a time there was interest in making it into a movie but apparently the family saga didn't translate well. Most recently, HBO was going to do it as a series. They had an amazing cast that included Dianne Wiest, Chris Cooper, Ewan MacGregor, Maggie Gyllenhaal, Rhys Ifans and Greta Gerwig.  The story follows  a family over a fifty-year time period. It starts with the aging parents but apparently goes back and forth in time. Unfortunately the format was too tough to adapt so HBO dropped it last month. BUMMER! I really wanted to see that. Oh well, I'm gonna read the book anyway. I'm enjoying Enid - the mother who shares a moniker my dear old mum!

Another book on my list to read, and also slated for HBO-dom is The Art of Fielding by Chad Harbach. They paid him a ton of money for the film rights and I'm hoping this is one that HBO goes ahead with.
