<P> In March 2011, Eleanor Tomlinson was cast opposite Nicholas Hoult as the princess and Ian McShane was cast to play her father, King Brahmwell . Two days later, New Line and Warner Bros. announced a release date of June 15, 2012 . </P> <P> Principal photography began on April 12, 2011, in the British countryside . In May 2011, production moved to Somerset, England for two weeks with filming scheduled in Wells, Cheddar and secret locations in the county including scenes filmed at Wells Cathedral . Also in May, scenes were shot at Puzzlewood in the Forest of Dean near Coleford, Gloucestershire . Puzzlewood, which features unusual tree and rock formations, has previously been used for filming of the BBC TV series Doctor Who and Merlin . The same forest is said to have inspired J.R.R. Tolkien to write The Hobbit . Later that month, filming took place at Norwich Cathedral in Norwich, Norfolk . </P> <P> About the performance - capture process Singer stated, "It's fascinating...It takes you back to play - acting as a kid in your living room because you are running around and having to imagine that you are in Gantua and imagine that there are these weapons and all these giant things . But there's nothing when you are there other than styrofoam and blocks . It forces the actors to regress to when they would play - act as kids or do minimalist theatre . But in that way it's fascinating - I can see why Robert Zemeckis and James Cameron have started to shoot pictures this way". </P> <P> In January 2012, Warner Bros. moved back the release date by nine months, from June 15, 2012, to March 22, 2013 . The Hollywood Reporter stated: "Warner can likely afford the move because of Christopher Nolan's The Dark Knight Rises, which opened in July . And moving the film back gives the studio more time for special effects, as well as a chance to attach trailers for it to Peter Jackson's Christmas tentpole The Hobbit: An Unexpected Journey". In October 2012, Warner Bros. again moved the release date, this time to March 1, 2013, three weeks earlier than the previous date . Warner Bros also changed the title of the film from Jack the Giant Killer to Jack the Giant Slayer . </P>
