The pub featured as The Greyhound is Hennessy's Bar on Castle Street in Tralee, County Kerry. The external signage was changed for just one day. All the exterior scenes featuring the pub were filmed during that 24 hour period.
When this film landed on Netflix UK it became the most watched new movie on the platform for that week. It knocked off Cattiverie a domicilio (2023) - also starring Olivia Colman.
