PrimEdge, Inc. announced that its subsidiary, Orangebox Entertainment has finished post production for the upcoming theatrical release, Return to the House on Haunted Hill, from Dark Castle Entertainment. The film is due to be released in September 2007 and distributed by Warner Bros. Pictures.

Dark Castle Entertainment was formed in 1999 by Joel Silver and Robert Zemeckis as a division of Silver Pictures, a production house affiliated with Warner Bros. Joel Silver and Robert Zemeckis are two of the most successful producers and preeminent filmmakers in the motion picture industry today. Their credits include: Lethal Weapon, Lethal Weapon 2, Lethal Weapon 3, and Lethal Weapon 4, Die Hard, Die Hard 2: Die Harder, Conspiracy Theory, Forrest Gump, Contact, "Who Framed Roger Rabbit?" Romancing the Stone, Death Becomes Her, Back to the Future, and the "Matrix" Trilogy, while their combined gross revenues from their films are a staggering $4.8 billion.

When first formed, the goal of Dark Castle Entertainment was to remake William Castle horror films from the 1950s and 60s. Dark Castle Entertainment's first film to debut was House on Haunted Hill, a remake of the late William Castle classic 1958 film of the same name which originally starred Vincent Price. Since then the company has expanded into producing original material along with the remakes.

Dark Castle has gone on to produced a series of successful horror films, including Gothika, starring Academy Award winning actress Halle Berry, House of Wax, and the upcoming The Reaping, starring two-time Oscar winner Hilary Swank.

Brian Schuster, President of PrimEdge, said, "Since last year we have continued a significant uptrend of garnering more and more work from the leading Cable, Satellite, and Television Networks, as well as the leading Film Producers, and the Major Studios throughout the industry. Completion of this current project, from yet another leading film producer and major studio, is another undeniable example of the outstanding reputation Orangebox Entertainment continues to build and reinforce each and every day with its state-of-the-art next generation post production work."
