Steven Spielberg has finished shooting his big-screen version of the iconic Belgian comic-book series "Tintin," producer Peter Jackson said.

"The Adventures of Tintin: The Secret of the Unicorn" stars Jamie Bell as Tintin, an intrepid young reporter whose relentless pursuit of a good story thrusts him into a world of high adventure. Set for release in late 2011, the movie also features the voice talents of Daniel Craig, Andy Serkis, Simon Pegg, Nick Frost, Gad Elmaleh, Toby Jones and Mackenzie Crook.

"'Tintin' is great. It's made. The movie is cut together and now (we) are turning it into a fully rendered film," Jackson told the BBC, adding the motion-capture movie's computer animation could take up to two more years to complete. "So the movie, to some degree, exists in a very rough state."

Jackson's latest film "The Lovely Bones" is slated to open in U.S. theaters next month. His other films include "King Kong" and "The Lord of the Rings" trilogy.
