he BBC’s Jane Austen reimagining The Other Bennet Sister returns for its final instalment on Sunday night, bringing Mary Bennet’s coming-of-age story to a close.

In an exclusive interview with HELLO!, Ruth and her on-screen daughter, Ella Bruccoleri, revealed one of the most memorable moments from filming – an “incredible” cast trip to Barry Island, inspired by Ruth’s iconic BBC sitcom.

A Gavin & Stacey-inspired day out

Filming for The Other Bennet Sister took place across Wales, so it was perhaps inevitable that the cast would make the pilgrimage to Barry Island – one of the most beloved locations from Gavin & Stacey, in which Ruth plays Nessa.

“Ruth arranged it all – it was incredible,” Ella told HELLO!. Ruth explained that the idea originally came from their co-star Richard E. Grant, who plays Mr Bennet in the period drama and who was particularly keen to visit.

“He’s quite a big Gavin & Stacey fan and he really wanted to go to Barry,” said Ruth. “And the only time we could go was at seven o’clock in the morning. So we drove down there, we had ice cream, we went to Marco’s cafe and he was just like a kid on Christmas morning.”

Word quickly spread among the rest of the cast, prompting Ruth to organise a second, larger trip – in true Nessa style.

“Ruth hired Dave’s coaches and was at the front of the coach, singing to us all. It was amazing,” said Ella. “We got to Barry, swam in the sea, then Ruth got Marco’s cafe to stay open for us. We all had ice cream and coffee, and we stopped off at the Gavin & Stacey house.”

Ruth added: “I’m not gonna lie, Dave’s coaches is not the most comfortable form of transport – it took us about three hours to get there, but it was still great!”
