The Unlimited bus is a branded double decker Routemaster, which has been transformed to resemble the interior of a Cineworld cinema, with customised features including signature red cinema seats, large screens, and a refreshment counter with soft drinks, popcorn and pick 'n' mix.
Cineworld's unlimited cinema package offers entry to movies for a set price per month, alongside discounts off cinema snacks and drinks nationwide.
Taking place twice per day over four days from 31 May until 3 June, the Cineworld Unlimited Movie Tour starts its journey at Hyde Park and lasts for one hour and 45 minutes, hosted by a professional tour guide.
It will take visitors through London’s landmark movie sites including Blackfriars Bridge, which will appear in Mission Impossible: Fallout, Buckingham Palace, featured in the upcoming Mary Poppins Returns and Trafalgar Square, which was seen in last year's Wonder Woman.
