SHE'S GOT MY BACK|

Sheridan Smith and Céline Buckens star as sisters on the edge when one of them goes missing after a plane crash

Sheridan Smith is S jumping in at the deep end for Paramount+ thriller The Castaways, starring as Lori, a holidaymaker who is stranded on a remote tropical island after surviving a plane crash.

The drama reveals what happened to Lori after the crash and follows her sister Erin, played by Céline Buckens, as she tracks down her missing sibling in Fiji.

Despite filming in Greece, Sheridan, 42, admits shooting The Castaways wasn't much of a holiday thanks to her fear of water. "I was terrified of water and I'm in water for most of the show," she says, laughing. "It was a challenge - I couldn't even go underwater without holding my nose. I had to have quite a few sessions with the stunt guys, first in a swimming pool and then in the sea. But now I'm cured!"

She adds that the whole experience, which was physically demanding, turned her into an action woman.

"I really enjoyed it more than I thought because I usually don't even like to run for the bus," she says. "I lost weight and I got fit - I was running up and down the beach. At first, I had a stitch but by the end I was loving it. It gave me a kick up the bum. I would definitely love to do more of this genre.
