In hiring Peter Jackson, the Oscar-winning director of the "Lord of the Rings" trilogy, to remake the monster classic "King Kong," Universal Pictures took a daring leap, paying him $20 million to direct, produce and be the co-writer of the film.

With seven weeks to go before the movie's release, the risks are becoming clearer. After seeing a version of the film in late September at Mr. Jackson's studio in New Zealand, Universal executives agreed to release "King Kong" at a length of three hours.
