LONDON — Sophie Okonedo, Alicia Silverstone, Bill Nighy, Mickey Rourke and Damian Lewis have been cast in “Stormbreaker,” the movie version of Anthony Horowitz’s bestseller that starts shooting Sunday.
Brit teen Alex Pettyfer will play reluctant spy Alex Rider in the pic that will feature Ewan McGregor in a cameo.
Missi Pyle, Ashley Walters and Sarah Bolger will also star in the story of a 14-year-old orphan who finds himself forced to work for MI6 when his uncle and guardian, himself a secret agent, is mysteriously killed.
Geoffrey Sax (“White Noise”) directs the film, which was pre-sold to the Weinstein Co. for North America and Entertainment Film Distributors for the U.K.
Co-financing comes from the Isle of Man Film Commission, VIP Medienfonds and the U.K. Film Council’s Premiere Fund.
Producers are Mark and Peter Samuelson, along with Steve Christian of the Isle of Man and Andreas Grosch of VIP. Capitol Films is selling international rights.
“Stormbreaker” is the first in a series of six Alex Rider books so far. Horowitz, whose screenplay credits include “The Gathering,” adapted his own novel.
Pettyfer played the title role in the recent ITV telepic “Tom Brown’s Schooldays.”
