Two men who say they were barred from riding a roller coaster at Universal Studios Hollywood because they are missing limbs have sued the theme park.

Angel Castelan, whose forearms were amputated after an electrical accident as a child, and Marvin Huezo, whose legs were amputated after a car accident, say they were kept off Revenge of the Mummy: The Ride, an indoor roller coaster.

The suit, filed last month in U.S. District Court in Los Angeles, contends the men were kept off the ride in violation of the Americans with Disabilities Act.

A spokeswoman for Universal Studios Hollywood said the park does not comment on pending litigation.

In the suit, Castelan said he is a longtime fan of the theme park and had ridden the roller coaster several times. But in October 2010, Castelan said, ride operators told him he could not ride the roller coaster because he does not have hands to grip the safety bars.

Castelan, according to the lawsuit, returned to the park in 2011 with Huezo, and operators of the Mummy ride barred both men, saying a new policy requires that all riders have at least one hand and one leg.

The suit seeks unspecified damages and asks a judge to order the park to change its policies regarding access to the roller coaster and complete other fixes to make the park accessible to guests with disabilities.
