Blockbuster directed by Bob Hoskins and Richard Attenborough to shoot in city
Mediaeval action thriller Ironclad, due for release next year, will see a host of Hollywood stars visit the city for filming.
Screen legend Bob Hoskins is set to direct the £20 million flick alongside Jurassic Park actor Richard Attenborough.
And Paul Giamatti, who had an Oscar nomination for his role in Cinderella Man, has been lined-up for a leading role.
Filming is set to start on October 14, with Oystermouth Castle in Mumbles chosen as one of the prime locations by bosses.
The popular tourist hotspot will be used to shoot a number of battle scenes before filming ends in December.
Sites across South Wales are also set to feature, including Caerphilly Castle. And the Dragon Studios in Bridgend are being used to film indoor scenes for what will be the venue's first-ever film shoot.
An inside source said: "To have a full-on mediaeval blockbuster shooting in Swansea is amazing news for the city.
"Lots of local actors are hoping to land fairly big parts in this, so it's likely to be a massive boost for the city and very exciting for movie fans.
"Everyone involved is really excited that Bob Hoskins and Richard Attenborough are directing."
William Mosely, who played Peter in the recent Narnia films, is on the cast list alongside Rome actor James Purefoy.
Purefoy is playing a member of the Knights Templar in the flick, which is set in the 13th Century.
His character defends Rochester Castle in the story against an army led by the ruthless King John, played by Giamatti.
Auditions for secondary roles were held in Cardiff last weekend and around 25 actors have this week been waiting for call backs.
