Just read that Paramount Pictures has bought the rights to make John Scalzi's Old Man's War into a movie.

If it's a success and goes through the entire storyline with Ghost Brigades as the sequel, I wonder whether they'll use The Last Colony to wind out a trilogy, or use the alternate version of that by following Zoe's Tale? Perhaps a combination of both.
For those who haven't read this series (and I highly recommend it), The Last Colony and Zoe's Tale are the same story from different perspectives. The Last Colony follows the actions/POV of John Perry (protagonist from Old Man's War) while Zoe's Tale follows the same plotline from the POV of Perry's adopted daughter Zoe (introduced in Ghost Brigades).
The idea was also done successfully by Orson Scott Card in Ender's Shadow - the telling of Ender's Tale from the POV of one of Ender's lieutenants - Bean.
Regardless, let's just hope that the translation from Scalzi's masterful story to the big screen doesn't crash and burn.
