Mike Newell, who directed Harry Potter and the Goblet of Fire, has been offered the Prince of Persia: The Sands of Tme directing job, according to Variety.  The property is videogame-based; First Second has a graphic novel (see 'First Second Has Prince of Persia'). 

Although there's a script, Prince of Persia is not one of the films that's being rushed into production without the benefit of rewrites.
