Footage of thousands of tourists and holidaymakers stranded outside Disneyland after a power cut affected the Californian theme park.

According to reports, tourists were stuck on rides and had to be escorted out after a transformer issue took out power in portions of the Toontown and Fantasyland areas.

"Never having seen security lines longer than 10-20 people in the past, this looked like an onslaught of a mob pushing their way into a safety zone, reminiscent of a zombie horror film," the filmer told Newsflare.
