Prince of Persia: The Sands of Time/Fridge

Fridge Brilliance

 * It's a small one, but one of the main themes in the movie is the importance of brothers and brotherhood. In the original Prince of Persia game, Jordan Mechner (who helped write the film) used photos of his own brother to create the Prince's sprite. Jordan's brother brought the Prince to life. Neat, huh?
 * Related to the lack of sand zombies: If Dastan could extract their Sands of Time, he'd probably just abuse the Dagger of Time at every pivotal plot point. Perhaps that's why they weren't in the movie?

Fridge Horror

 * What difference is there between Nazim and Dastan holding the dagger in the Sandglass. They both wound up back in time like they wanted. What if the present WAS destroyed but a little side effect of time travel is it undoes that... Still BILLIONS of lives are on his head, if only for a moment. And that was the gods' plan. Now their waiting to see if Dastan felt any remorse for killing all life on Earth after his second chance. Heck maybe Sand Demon would pursue him in a sequel who are basically the doomed masses of the alternate future.
 * Uh hello! Dastan was trying to stop NIZAM from killing billions of people by messing with the past. Which I'd like to point out, HE DID! I'd also like to point out that Dastan wasn't interested in useing the power of the Sandglass, he was just trying to stop Nizam from doing so.
