Crews were hired to remove and hide snowfall and snow accumulation during filming because the film was shot in the winter months. In some indoor scenes, extras were paid to block the windows and doors so the snowfall wouldn't be visible on camera.
Kristen Wiig and Bill Hader were only on set for four days. All scenes with their characters, Paulette and Bobby, had to be condensed and shot quickly due to their commitments to Saturday Night Live.
Director Greg Mottola originally planned to shoot the movie in the real Adventureland park, but later decided against it since the park had been so drastically remodeled since he had worked there.
The real Adventureland park upon which the movie is based is located in Farmingdale, Long Island, New York.
Adventureland was filmed in Pittsburgh, Pennsylvania. The amusement park in the movie is known as Kennywood Park. The rides shown in the movie are actual rides, although the names of the games have been changed.
