Marley & Me is an awesome story for dog lovers. I read the book and I saw the movie. I loved them both and I cried for both. It also makes me think twice about getting a lab, but any dog can be a bit of a problem without training!
I just heard today that there is going to be a direct to DVD and Blue-ray prequel called Marley & Me: The Terrible 2s. You can see the preview on newly released DVDs like Alvin and the Chipmonks: The Squeakquel and Fantastic Mr. Fox. I know nothing of the story line, but it seems it will focus on the time when Marley was a mischievous puppy.
Here is a preview, it is not the best quality:
If you visit the official movie page, marleyandmemovie.com, it only has the preview for the first movie and Marley licking the screen.
Lastly, here is a video of an interview with the dog who played Marley in the movie, Jonah:
I have found information on IMDB about Marley and Me: The Puppy Years – with a subtitle that says “also known as Marley and Me the Terrible 2s”. Marley and Me: The Puppy Years has a release date of June 1, 2011. There is not much more information than this listed. To check out it out, visit imdb.com.
Update 2: Marley and Me the Puppy Years comes out this week on Tuesday, 1/3/2010. Best Buy is advertising the blueray (or so the ad seems to show) for $7.99.
