The film is based the Cornish tale of "Jack the Giant Killer." That fairy tale, according to Wikipedia, features "a plucky lad who slays a number of giants during King Arthur's reign." In 1962, a feature-length film version starring Kerwin Mathews was released. That version made extensive use of stop-motion animation similar to that used by Ray Harryhausen.
The new version of the tale was originally dubbed as the earlier ones, "Jack the Giant Killer," but the name was changed, perhaps to soften it somewhat. The film, is directed by Bryan Singer ("X-Men: First Class" and the upcoming "X-Men: Days of Future Past"), and stars Nicholas Hoult, Eleanor Tomlinson, Stanley Tucci, Ian McShane, Bill Nighy and Ewan McGregor.
As described by Wikipedia:
When Jack, a young farmhand, accidentally opens a gateway to the world of Giants an ancient war restarts as the giants, thought only of as legend, try and reclaim the world they lost centuries ago. Jack is forced into a fight to not only save his own life, but that of those in the kingdom and that of the princess.
The film has had a long road to reach the big screen. Development began in January of 2009 with the hiring of D. J. Caruso to direct the film. By August of 2009, Caruso was replaced by Singer, who in April of 2010 hired Christopher McQuarrie to rework the script.
