Jordan Merchner is an interesting game developer most notably because he works in so many other mediums. He also designed the (arguably) timeless Sands of Time videogame. I haven't seen the film, but friends steered me away from it. My plan: read the original screenplay and see just how much has changed. Because that's Hollywood baby!
Edit: Script was entertaining, but not worthy of any awards. The prince comes off a bit misogynistic like in the game. His adaptation to make the plot run a cleaner in a film format works quite well, but I won't spoil much. It's worth the hour or so it took to read it.
