Stanley Tucci and Bill Nighy cast in Jack the Giant Killer

Two thesps sign on for Brian Singer's fantasy

Bryan Singer's Jack the Giant Killer has got its first two official cast members in the form of Stanley Tucci and Bill Nighy.

Tucci will be playing villain Roderick, an advisor to the king. His chilling villain in The Lovely Bones was one of that film's few genuine successes, and he received an Oscar nom for his performance.

Nighy is set to play Fallon, the leader of the giants. The character is apparently two-headed, with John Kassir joining Nighy in the role.

Playing CGI-augemented villain Davy Jones in two Pirates of the Caribbean franchise entries brought Nighy great acclaim.

Tucci will be seen later this year in Captain America: The First Avenger, and Nighy's reprising his role in Harry Potter and the Deathly Hallows: Part 2.

Despite rumours that Kick-Ass star Aaron Johnson would be playing Jack, the lead character has yet to be cast.

The movie, which is co-scripted by Usual Suspects writer Christopher McQuarrie, is a revisionist take on the 'Jack and the Beanstalk' fairytale. In this version, Jack is tasked with rescuing a kidnapped princess who has been taken to the giants' kingdom.

Singer is also acting as a producer on the upcoming X-Men: First Class. His last movie with McQuarrie, Valkyrie, received a lukewarm reception from critics.

Jack the Giant Killer is set for release sometime in 2012.
