Warner is showing off its new interactive feature, dubbed "Navigational Cinema," at the website for the direct-to-video "Return to House on Haunted Hill" which is due out October 16th. The interactive feature is exclusive to the HD discs, so almost anyone with a HD player can join in on the fun. Navigational Cinema allows you to choose from multiple story lines at key points in the film and click your way through to one of over 200 endings. If that's too much suspense for you, there are more, um, passive extras on the release as well. Follow the link for a clip of Navigational Cinema in action.
