Movie World on the Gold Coast has closed one of its biggest rides to find out why 20 thrill-seekers were left dangling.

It was an hour-and-a-half before they could be brought down from a faulty rollercoaster.

Nobody was hurt but some felt the effects of 30 degree-plus heat.

General Manager Greg Young says the ride passed an audit last year after four people died at Dream World.

"This is a typical safety stop for us... Our team are trained to do these evacuations."
