Six weeks of studio and location filming around the Isle of Man by the star-studded cast and crew of Stormbreaker has finished.
Mr Horowitz wrote TV show Midsomer Murders before creating Alex Rider
The film is based on the adventures of teenage super-spy Alex Rider.
British author Anthony Horowitz's six books about Rider's adventures have sold millions of copies world-wide.
The impressive crew and cast, which includes Ewan McGregor, Bill Nighy and Mickey Rourke, now have six more weeks of filming in and around London.
Producer Marc Samuelson hosted a visit to the set in Island Studios for Air Marshal Ian Macfadyen, and Alex Downie, Minister for Trade and Industry.
During the visit, the party watched some filming and met the star of the film, 14-year-old Alex Pettyfer, and Mr Horowitz.
"A growing number of local people are now working on the films produced on the island and, in addition to using local crew, each film is obliged to take on four local individuals in trainee roles," said Mr Downie.
"Consequently, our indigenous skill base is constantly improving and local youngsters are getting fantastic opportunities for developing their chosen specialities."
Mr Samuelson said: "We'll be very sad to leave the island.
"It's always a pleasure to work with Isle of Man Film and to shoot on the island.
"Manx people are very kind to us and I hope we will be able to repay some of that kindness by making Stormbreaker one of the biggest hits of next year."
