Dave Prowse Goes Back Under the Mask
Last summer in London, David Prowse donned Vader's helmet for a special shooting of footage for a new Hasbro European Star Wars board game called Star Wars: The Interactive Video Board Game. Hasbro spared no expense to bring back the original for the shoot. "They wanted it to be as authentic and as close to the film as could be," says ILM's Nelson Hall, who served as costume supervisor and Lucasfilm liaison on the shoot. Hasrbo utilized all original costumes and props, hired the original set-makers, Dick Geroge Productions, to create the scene, and even coaxed original Star Wars cinematographer Gil Taylor, now in his 80s, out of retirement to shoot the footage. They even procured James Earl Jones to do Vader's voice.
In the game each player leads an assault on the Death Star. Game pieces are moved around the board as players get closer and closer to the Death Star's reactor shaft in hopes of disabling it. While the game is being played, an hour-long videotape plays a shot of the Death Star approaching a Rebel Planet. At completely inopportune moments the exclusive new footage of Vader suddenly interrupts the gameplay with severe repercussions for the players.
Currently the American release of the game is planned for the fourth quarter of '96 as a Toys 'R Us exclusive.
