Surviving cast members from the hugely popular Carry On films came together at their old studios to remember fondly their brand of saucy seaside humour.

The actors also used the occasion to pay tribute to Sid James, famous for his cackle and cheeky one-liners, on the 22nd anniversary of his death.

The British Comedy Society unveiled plaques to James and other Carry On legends Kenneth Williams, Hattie Jacques and Charles Hawtrey.

The 31 films, the first of which was made in 1958, carried the standard for camp performances and outrageous innuendo and turned the actors and actresses into household names.

Surviving members of the main team, Barbara Windsor, June Whitfield, Leslie Phillips and Jack Douglas, attended the gala at Pinewood Studios, Hertfordshire to unveil the tributes.

They were joined by fellow Carry On veterans Fenella Fielding, Lance Percival, Suzanne Danielle, Liz Fraser and members of the crew.

Gareth Hughes, chairman of the BCS, said there were many reasons why Carry On films had been such a hit.

"As one person once said they were naughty but never dirty," said Mr Hughes.

"There was a wonderful team of writers and a wonderful ensemble cast who kept the British film industry going through a fallow period, along with the Bond films."

Barbara Windsor at the unveiling

Barbara Windsor, who unveiled the plaque to Kenneth Williams, said: "There's not a day goes by when I don't think about Kenny Williams.

"In my late 40s I found it difficult at casting interviews because people would still think I was as young as I appeared in the Carry Ons.

"I would go for a part that was my age but they would have seen Carry On Camping the night before and say I was far too young."

June Whitfield added: "The Carry Ons were a nudging sort of humour, like seaside postcards, not at all politically correct which was always a good thing.

"They were a sort of innocent kind of humour. I think today's kind of humour is far less innocent and sometimes very vulgar."
