AN INCREDIBLE abandoned Marvel film set has been found hidden deep underground by explorers.
Some 300m below ground and 8km into the tunnels, the pair discovered the Fantastic Four Marvel movie set - complete with an American school bus, a stage, and a lift car.
Lord of The Rings and Mission Impossible are also believed to have been filmed down there.
The two friends, who don't want to be named, said they entered the mine in the Derbyshire Dales after spotting an opening.
One of the explorers said: "The mine once had huge concrete blocks over the entrance but I was hiking and noticed they'd been removed."
Despite finding the lead mine tunnels quite "scary" the pair spent four hours inspecting the area, which they said was "unbelievable".
One explorer added: "We were walking along with our torches and we suddenly found this area all built up and an old American bus just sitting there.
"The lighting rigs were there on scaffolding and a map of where they wanted all the lights to be.
"It's very bizarre to see an elevator car just sitting in the middle of a roadway, and a stage in front of the bus."
The pair also discovered "all sort of machinery" that was likely used to set up, and a cabin with a microwave and kettle.

Pipes the film crew would have used to keep the air clean were also found, which one of the explorers warned meant "there's a risk of radon gas down there."
One of the pair said: "It was quite something to see the film set - it wasn't what we had expected at all."
This follows the Sun's report on the Sandstone caves near the Black Country which were once home to England's last troglodytes.
Kinver Edge is a high heath and woodland escarpment on the Staffordshire-Worcestershire border.
A network of cavernous houses were carved into its three soft red sandstone rocks – Holy Austin, Nanny's and Vale's.
The rock houses were inhabited until the 1960s and are now owned by the National Trust.
The homes at Holy Austin were restored in 1993 to represent life in the rock houses in the early 1900s.
The original home of Mr and Mrs Fletcher at the lower level was reconstructed based on photographs and memories.
