Called DVDKey, the technology from InterActual grants viewers access to content online when the DVD is placed in a PC and played back using an InterActual-compatible DVD player.

The online bonus features include Create your own journal, The Lord of the Rings style; Constructing Middle Earth; and Cast and Crew Palantir.

InterActual’s DVDKey allows for compelling bonus feature content that delivers the vision and detail that is expected of any derivative work based on The Lord of the Rings motion picture trilogy, said Gunthar Hartwig, program director and producer for InterActual. Because viewers access these bonus features online, content can be updated and refreshed even after the DVD has been released.

InterActual-compatible players for Windows PCs include InterVideo WinDVD 6 with the InterActual Pack option, and the free InterActual Player included on the Extended Edition DVDs. WinDVD 6 users with the InterActual Pack can view The Return of the King enhanced features in the WinDVD interface with no additional software installation required.
