Not long after Warner Bros. was reportedly getting cold feet with the swelling budget of David Dobkin’s Arthur & Lancelot, it looks like the studio has officially hit the pause button. The film, starring Kit Herington (Game of Thrones) and Joel Kinnaman (The Darkest Hour) in a reimagined Arthurian legend, was supposed to open March 15, 2013. Dobkin (The Wedding Crashers) reportedly informed cast and crew that it “wasn’t looking good,” although studio insiders confirm they’re trying to make the project work. Warner envisions the tone of Arthur & Lancelot to be in a similar vein to their Sherlock Holmes franchise, but will have to negotiate budget and scheduling difficulties. Herington, will return to Game of Thrones this spring while Kinnaman is expected to segue into the film shoot after wrapping on AMC’s The Killing. The project may move forward without one or both of the actors. Hit the jump for news regarding the delay of Bryan Singer’s Jack the Giant Killer 3D and Rock of Ages.THR reports that the fantasy film, Jack the Giant Killer 3D will be pushed back to March 22, 2013, a delay of nine months from its original June 15th opening of this year. This move puts it out of the blast radius of Christopher Nolan’s The Dark Knight Rises, which opens this July and will likely dominate the summer box office. Additionally, the new release date allows more time to fine tune special effects and gives the Warners an opportunity to attach trailers to Peter Jackson’s The Hobbit: An Unexpected Journey. Jack and the Giant Killer 3D stars Ewan McGregor, Stanley Tucci and Nicholas Hoult.In a smaller schedule tweak, Warner Bros and New Line have pushed back Adam Shankman’s Rock of Ages from June 1st to June 15th of this year. The film stars Tom Cruise, Julianne Hough and Diego Boneta. rock-of-ages-movie-poster-01
