Some shops have been boarded up and street art has been used to transform Alton into a post-apocalyptic town.

The Market Street up to Lenten Street, and The Market Square, are closed to the public, along with Anstey Field and parts of Anstey Park.

The film is expected to be released in 2025 and will see the surviving Garrity family members leave the safety of the Greenland bunker and embark on a journey across a frozen wasteland to find a new home.

Gerard Butler, Scottish star of 300 and Olympus Has Fallen, plays John Garrity.
