Winchester Films was a British production company. It was started in March 1993 and was listed on the Alternative Investment Market to raise the capital needed to build an effective portfolio of films and TV programmes. In the late 1990s and the early part of the 21st Century, Winchester Films acquired produced many British films and acquired distribution rights to films from other countries. It also expanded into the US, setting up an office in Los Angeles in order to make connections with the Hollywood crowd. This led to Winchester Films being granted distribution rights to Heartbreakers.
