Tip from Achokablog:
News.Scotsman.com--15-year-old Alex Pettyfer will play Alex Rider in the movie version of Anthony Horowitz's book, Stormbreaker. If the movie is a hit, count on more movie sequels from the popular series.
I cannot quite see Alicia Silverstone as Starbright...but Ewan McGregor as Uncle Ian is a nice idea.
I daresay, photos of Pettyfer will not be so difficult to find in the future.
