This movie looks awesome, but we still have a long wait: it’s not due out until May 2010

Apparently, another game will be released by Ubisoft to coincide with the movie, “Prince of Persia: The Game of the Movie of the Game”

In the meantime, you can check out the original game:
1) http://www.abandonia.com/en/games/10 – the DOS version
2) http://jayisgames.com/archives/2004/06/prince_of_persi.php – an online Flash version
3) http://www.dosgamesarchive.com/download/prince-of-persia-4d/ – a faithful remake but with added challenges:

“The tortuous difficulty level of this fanmade version makes it a perfect game for those who finished the original game and are looking for a real challenge to save the princess.”

Follow the link to see screenshots and a video of the game.

Also, here’s an online Flash version.

The Prince of Persia Unofficial Website has loads of information on all versions of Prince of Persia – an excellent resource!
