The Sensurround effects were recorded on location for "Rollercoaster" rather than being created in post-production as with the other Sensurround movies.
Steve Guttenberg:
Uncredited, as the messenger who brings the plans for the Revolution Rollercoaster ride to Hoyt and Calder at at Six Flags Magic Mountain Amusement Park.
Attractions at the King's Dominion amusement park in Doswell, Virginia seen in the film included a replica of the Eiffel Tower, an antique modern mono-rail, a Lion Country Safari monorail, and the Rebel Yell twin-racing rollercoaster.
The Young Man places the remote bomb on the first roller coaster underneath the main guide rail of the track, but allows the ride to run several times before detonating it. In reality, the up-stop wheels or side wheels of the next train to pass through the course would have knocked the bomb out of place or destroyed it.
The last portion of the movie at Magic Mountain is depicted as taking place on July 4th but in fact it's easy to tell the filming was done during the winter months. The trees in the park are all dormant.
