The One That Got Away is set and filmed in Pembroke Dock
The thriller storyline of The One That Got Away is set in a Welsh seaside town, and the production chose the perfect location to replicate the scenery and vibe the story requires. The series, which takes place in Pembrokeshire, enhances its authenticity by filming most scenes in the same region. The Welsh county, renowned for its stunning castles and expansive, rugged beaches, significantly contributes to the story's tension and atmosphere.
The new BBC thriller series filmed most of its scenes in Pembroke Dock, situated along the banks of the River Cleddau. This location serves as the focal point of the plot, where the nurse was murdered. Once a small fishing village, Pembroke Dock has grown over the years and now features several historical sites, including the Royal Dockyard on Britain's west coast.
The One That Got Away primarily focused on the areas surrounding the River Cleddau, such as the Cleddau Bridge. This isn't surprising, given the show's original Welsh title, Cleddau. The bridge's main span is 213 meters long and carries the A447 road, which connects Pembroke Dock to Neyland. According to the BBC, the series was also reportedly filmed in other locations around South Wales.
Pembrokeshire is not a new filming destination; it has already served as the backdrop for various TV shows and films. For example, parts of Harry Potter and the Deathly Hallows were filmed at Freshwater West Beach, while Snow White and the Huntsman was shot in Marloes Sands.
