ITV’s carefully assembled cast of stars will go face-to-face with one of nature’s deadliest predators tonight (August 11).
Shark! Celebrity Infested Waters will come to an end with the dive the show has all been building-up to. The famous faces are set to swim with ‘18-foot tiger sharks’ in the final episode.
ITV has confirmed the start time for the last episode of the reality show. It has been airing on Monday nights throughout July and August but the full boxset is also available on ITVX.
A cast of famous faces from the world of TV, music and comedy has been assembled for the show, which sees them train to swim face-to-face with sharks. Dispatched to the Bahamas they have been teamed-up with experts Danni Washington and Tristain Guttridge and shark attack survivor Paul de Gelder to help them prepare.
Throughout the season they have already had encounters with the likes of hammerhead sharks. However for the final episode they will swim with tiger sharks, which are known for having a wide ranging diet including smaller sharks, birds, fish, dolphins and more.
The Florida Museum has a report which found that “the total number of unprovoked shark bites worldwide remains extremely low”. Just 47 unprovoked attacks were recorded worldwide in 2024.
But who is in the cast and where do you recognise them from? Here’s all you need to know.

From his titular show to Comic Relief and most recently Prime Video’s Lord of the Rings TV show, you will have definitely seen Sir Lenny on your screen plenty of times. He said: “When the question was put to me, would you like to go on an adventure of ecology and exploration involving sharks, I didn’t have that cartoon special effect where my eyeballs jumped out of my head. I actually considered it and thought, actually, I’d love to do that.” | Plimsoll Productions/ITV Photo: Plimsoll Productions/ITV

6. Lucy Punch
Lucy Punch is an actor who has appeared in films such as Hot Fuzz, Bad Teacher and Into the Woods. However you probably recognise her from her role as Amanda in Motherland and its spin-off Amandaland - both on the BBC. She said: “I was really excited about being part of a new show like this. It has an important message and while traditional wildlife shows are preaching to the converted, the entertainment element of a show like this on ITV makes it family viewing and brings a whole new audience.” | Plimsoll Productions/ITV Photo: Plimsoll Productions/ITV

7. Rachel Riley
Rachel Riley has swapped Countdown for the Bahamas for this ITV series. She co-presents the famous Channel 4 show and its spin-off 8 Out of 10 Cats does Countdown. She said: “Over the last few decades, they're trying to show that sharks are worth more to people alive than they are dead. There's been loads of conservation work and research in that area.” | Plimsoll Productions/ITV Photo: Plimsoll Productions/ITV
