A production company is responsible for the actual production of a film, including funding, distribution to film studios and cinemas, and promoting the film. The authors chose Paramount Pictures as their production and distribution company because it is a large, well-known studio that could ensure their film was seen widely in cinemas across the UK. A distributor is responsible for releasing films to the public through theatrical screenings or home video formats like DVD. Paramount has its own distribution arm, making it a simpler option. The authors felt Paramount had a wide variety of genres it distributed and their psychological thriller would fit with films like Shutter Island the studio had previously distributed.
