A big-name directing duo has just landed a hot acting pair.

Simon Pegg and Nick Frost have just joined Steven Spielberg and Peter Jackson’s upcoming productions of Tintin. The two pictures, which will be filmed as 3-D performance-capture projects, is based off The Adventures of Tintin, a popular Belgian comic book series.

The Shaun of the Dead actors will play Thompson and Thomson, identical-yet-unrelated detectives who sport slightly different mustaches. The duo joins Andy Serkis (Lord of the Rings), who had already been cast as Captain Haddock. Meanwhile, the role of Tintin, the young reporter at the center of the stories, has not yet been filled. (A previous selection had to drop out due to scheduling conflicts.)

The first of the two planned Sony/Paramount co-productions will be helmed by Spielberg. Jackson will direct the second.
