The pre-production largely went without rehearsals as Olivia Colman doesn't like to rehearse too much, preferring to be more spontaneous in her performance. This actually aided first time actor Charlie Reid who was able to spark off his co-star and her differing takes of each scene.
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 Scandaleusement vôtre (2023) - also starring Olivia Colman.
