Closure (The X-Files)/Background Information

* crew had built two permanent stages, when shooting of the television series; these stages were five and six at . The crew also used stage eight as their "swing set". The first scene of this episode was shot in Griffith Park, above the playground for children. The first scene with the walk-ins rising up from their grave was a "tricky" scene, according to director . To get the kids into the graves, the crew told the children that the graves were actually forts, saying that the kids would not collaborate if they told them to lay themselves in a grave. ("Closure" audio commentary)
*The scene at April Air Force Base was shot in San Bernadino, California, at a closed airfield. Close to the airbase, there was a huge abandoned house complex, built and used by the United States military. This air force base was renamed April Air Force Base, since the producers could not use the name March Air Force Base. One of the shots set inside April Air Force Base was filmed at a sound-stage in Los Angeles. The scene at the restaurant was shot in a location on Sepulveda Boulevard, at a hotel that had been standing there for thirty to forty years. ("Closure" audio commentary)
