Yesterday: First look at 6,000-extra Danny Boyle film
The first look at a new Richard Curtis film featuring more than 6,000 extras has been revealed in a trailer.
Yesterday, directed by Danny Boyle, held an open casting call for a crowd scene held on Gorleston beach, Norfolk.
Experts believe its high profile could hand a boost to the region's film and tourism sectors.
The film imagines a world without the Beatles in which an aspiring singer-songwriter claims the Fab Four's hits are his own.
Filming also took place at Halesworth, Suffolk, and Clacton-on-Sea in Essex.
Julien Mery, a director of Film Suffolk said: "It's a fantastic advert for Suffolk in itself and I would be surprised if it didn't lead to an increase in film-induced tourism.
"People see these wonderful locations on the big screen and then come to visit them for themselves."
Mr Mery said it could also be a milestone for the regional film industry, by proving to production companies that the area has the skilled professionals for their projects.
Film writer Alex Paps tweeted about his excitement for the film.
