Casualty spoilers follow.
Casualty star Michael Stevenson has further teased upcoming underwater scenes for his character, Iain Dean.
First revealed on Stevenson's social media last month, upcoming scenes shot at the iconic Pinewood Studios will see paramedic Iain getting wet and wild.
The actor told Inside Soap: "Idris Elba was in the water tank the day before me! It was such a unique experience, it's like a whole film set underwater; you're doing everything the same as you would do above water. Although everybody is much better behaved!"

He added: "It's a big-budget episode, and we went to Pinewood to film some underwater stuff. It was just incredible, the history that runs through that building is amazing."

The actor also teased that the underwater scenes will form part of "a massive episode we've just finished filming that we've been talking about doing for quite a long time".
In his original Instagram reveal, the actor uploaded a snap of himself outside the Underwater Stage at Pinewood with the caption: "Feeling pretty bloody lucky to have spent two days filming at the legendary @pinewoodstudios. This is a dream come true for me to be on a studio lot steeped in so much film history."

While Stevenson chose not to expand on how his character ends up in a watery situation, he did add that he'd been working alongside an underwater crew, suggesting there could be a big stunt on the horizon.
Stevenson's co-star Kirsty Mitchell, who plays Faith Cadogan, has recently spoken about the possibility of a reunion between Faith and Iain, following Faith's issues with drugs.
"She still loves Iain, even though she hid it well towards the end," she said. "They're lovely together and the kids adore him, but it's difficult."
Casualty airs on Saturdays on BBC One and streams on BBC iPlayer.
