Actor Shia LaBeouf is occupying a lift in Oxford as part of an arts performance.
Aside from a break to give a talk at the Oxford Union at 8pm and brief exits to visit the toilet, LaBeouf is spending 24 hours in the lift.
He started at 9am on Friday and will remain in the lift until 9am on Saturday.
Viewers are able to watch the performance in a live YouTube stream entitled #ELEVATE.
The Hollywood star is joined by friends and musical collaborators Nastja Ronkko and Luke Turner, as well as other visitors to the building.
