Hundreds queued for the chance to take part in the film
About 500 movie hopefuls queued at a casting session to find extras for a remake of the 1947 film Brighton Rock.
The film, based on Graham Greene's 1939 novel and featuring Dame Helen Mirren, will be set in 1964 and filmed in Brighton and Eastbourne.
Saturday's casting session was held at the International Lawn Tennis Centre in Eastbourne. Another session is being held in Brighton on Sunday.
Poducers were looking extras to play Mods and Rockers and local characters.
They will be filling parts for day trippers and an array of girlfriends, housewives, parents, children and grandparents.
"I was hoping to see this many people here because we need about 300 to 400," said crowd assistant director Candy Marlowe in Eastbourne on Saturday.
"Then we have got two weeks filming in Brighton and we need about the same number again.
"We are also looking for specific people who could end up saying the odd thing.
"And we need at least 10 children every day we are filming in Eastbourne."
Filming in the town is to take place from 18 to 23 October.
Eastbourne was chosen for its traditional seafront, which has been promoted by the borough council as a film and TV location.
The 2008 film Angus, Thongs and Perfect Snogging was filmed and set in Eastbourne and the town has been used in EastEnders and Little Britain.
Dame Helen Mirren will star in the film as Ida Arnold
"The Film Liaison Unit has been a roaring success for Eastbourne during the past few years, attracting significant names to the resort," said councillor Susan Morris.
Earlier this year Eastbourne hosted a familiarisation trip for location managers, showing them Sovereign Harbour, the Napoleonic Redoubt Fortress and Eastbourne College's cloisters corridor.
Brighton Rock tells the story of teenager Pinkie who seduces a young waitress after she stumbles on evidence linking him and his gang to a revenge killing he committed.
The original 1947 movie starred Richard Attenborough in the lead role.
Mirren will star as Ida Arnold alongside Bafta-nominated actor Sam Riley playing the lead character Pinkie Brown.
Pete Postlethwaite and Happy Go Lucky's Andrea Riseborough will also star in the remake.
