Principal photography is underway in London on acclaimed filmmaker Bryan Singer's 3D epic action adventure "Jack the Giant Killer," with Nicholas Hoult in the title role of Jack, for New Line Cinema and Legendary Pictures.

"Jack the Giant Killer" tells the story of an ancient war that is reignited when a young farmhand unwittingly opens a gateway between our world and a fearsome race of giants. Unleashed on the Earth for the first time in centuries, the giants strive to reclaim the land they once lost, forcing the young man, Jack, into the battle of his life to stop them. Fighting for a kingdom, its people, and the love of a brave princess, he comes face to face with the unstoppable warriors he thought only existed in legend - and gets the chance to become a legend himself.

Nicholas Hoult and Bryan Singer recently collaborated on the Singer-produced "X-Men: First Class," for release later this year. "Jack the Giant Killer" also stars Eleanor Tomlinson as Princess Isabelle; Stanley Tucci as the deceitful Lord Roderick; Ian McShane as the besieged King Brahmwell; Bill Nighy as the giants' leader General Fallon; and Ewan McGregor as palace guard Elmont.

Bryan Singer will direct from a screenplay by Darren Lemke and Christopher McQuarrie and Dan Studney, story by Darren Lemke & David Dobkin. The film will be produced by Neal H. Moritz, David Dobkin, Bryan Singer and Patrick McCormick.

The creative filmmaking team includes Bryan Singer's longtime collaborators, director of photography Newton Thomas Sigel (X2: X-Men United) and editor John Ottman (X2: X-Men United). The production designer is Gavin Bocquet (Valkyrie).

"Jack the Giant Killer" is filming on location in and around London, and is scheduled for a summer 2012 release.

A New Line Cinema presentation, in association with Legendary Pictures, the film will be distributed by Warner Bros. Pictures, a Warner Bros. Entertainment Company.
