Katie Says Goodbye in not technically out in the UK. There isn't a dvd or anything. It's on amazon prime as an overnight rental its not Free to stream.
I'm hearing a Taiwanese/UK production called The Receptionist has a rape. Apparently it was released to UK cinemas in July 2018. I never heard of it I expect it was a very small and select theatrical release. Should be out soon.
