The prince grabs the dagger and ignites the screen.  We meet the characters, but what you really learn is that everyone in the movie wants the dagger because the holder goes back in time. The dagger holds the sands of time. Get it? The sands of time is the name of the  movie.

Prince of Persia: Sands of Time looks like a fun movie to watch. The movie opens May 28, 2010.
