A giant fire-breathing dragon went up in flames during a live performance at Disneyland in California.
Several videos posted on social media showed the 45ft stage prop ablaze as members of the audience were informed via the public address system that the show could not continue due to "unforeseen circumstances".
People were then evacuated from the area at the theme park in Anaheim.
There were no reports of any injuries, according to the fire service.
The fire broke out during a performance of Fantasmic, which promises "enhanced special effects, state-of-the-art projections and superb pyrotechnics".
In the show, Mickey Mouse conducts scenes from Disney classics, including Aladdin and The Lion King.
It includes a section in which the evil queen from Snow White conjures up some of the cartoon giant's most wicked villains, including the malevolent fairy Maleficent in the form of a huge flame-breathing dragon, which featured in Sleeping Beauty.
One person joked on social media: "Looks like Maleficent's evil plan backfired."
Disneyland have been contacted for comment.
