On Wednesday 13th May 2026, Prime Video shared a photo of characters Belly and Conrad, writing: 'Did you miss them? The Summer I Turned Pretty movie is now in production'.

Where is it filmed?

Bosses a keen to keep the filming location of the movie under wraps, writing on social media: 'We love the excitement, but sharing locations and visiting set disrupts filming and creates real safety concerns for our cast and crew. We’re working hard to create a protected bubble to make the best movie possible. Please help us protect the magic of Cousins until it’s ready to be shared. 💛'.
