others. Effects editor Zachary Tucker combined the elements created by the Texan LIDAR company with computer-generated graphics to make possible the scenes of time-travel experienced in the film. The explosion of the Stumpf was filmed using an actual New Orleans ferry in a portion of the Mississippi River sectioned off especially for the event; the occurrence took over four hours to prepare. Under the supervision of pyrotechnics expert John Frazier, the ferry was coated entirely with fire retardant and rigged with fifty gasoline bombs including black dirt and diesel, each one set to detonate within a five-second range. People and cars were added in later as elements of computer-generated graphics. Chris Lebenzon was largely responsible for moving clips from each of the sixteen cameras in place to create the sensation of an extended explosion sequence. The spectacular explosion actually caused no significant structural damage to the ferry; after a bout of sandblasting and repainting, the ferry was very similar to its previous state. The ferry was returned into service four days after the production of the film's scene concluded. During filming of the underwater car scenes, actual cars were dropped into the water; computer-generated effects were later added, simulating the entities' explosions. Compositing was done on the Autodesk Inferno special effects program. Similarities between Timothy McVeigh and Carroll Oerstadt Jim Caviezel's character, Carroll Oerstadt, seemed to mirror in several ways the story of Timothy McVeigh, a domestic terrorist who destroyed the Alfred P. Murrah Federal Building in Oklahoma City with a bomb in 1995. Caviezel and Scott did not deny this, and both admitted that the Oerstadt character was at least partly based on McVeigh. Ross Johnson of The New York Times also compared the ferry bombing at the film's beginning to the Oklahoma City bombing. Home media Déjà Vu was released on DVD and home video approximately five months after its release in American theaters, on April 24, 2007. In the two weeks succeeding the day of the DVD's release, the film was the second most purchased DVD in the United States. It was second only to Night at the Museum during this period in time. Special features on the disc include an audio commentary from director Tony Scott for both the film and its deleted scenes. The DVD cover also includes a "Surveillance Window" feature, which includes featurettes on the film's production in New Orleans. Soundtrack The track
