3 Aug – Despite its lacklustre reception and reviews the "Green Lantern" superhero movie received, Warner Bros' studio and its producers are moving forward with an upcoming sequel that is reportedly much edgier and darker similar to "The Dark Knight" Batman movie, according to a report by the Huffington Post's website. Warner Bros' film group president Jeff Robinov was quoted as saying, "We had a decent opening, so we learned there is an audience. To go forward we need to make it a little edgier and darker with more emphasis on action... And we have to find a way to balance the time the movie spends in space versus on Earth." Robinov also confirmed that Warner Bros. and DC Comics have every intention of producing a sequel to "Green Lantern", despite the average US $53 million opening with a disappointing worldwide gross of approximately US $160 million it managed to rake in. Warner Bros. has previously confirmed its plans to adapt characters from its DC Comics ownership, including Green Lantern, Superman, Flash and Wonder Woman, in a similar manner. Its Superman reboot, "Man of Steel", starring Henry Cavill, Amy Adams, Russell Crowe, Kevin Costner and Diane Lane, is scheduled for June 2013.
