StudioCanal UK (formerly Optimum Releasing/Home Entertainment/Classics) is a film distributor company working in the UK and Ireland. Due to them distributing films such as Tyrannosaur and Don't Be Afraid of the Dark, they would be the best bet for being a distributor for my film as they are probably one of the man distributors of independent British films.
The British film council is a charitable organisation established to help develop the british film industry and to invest n films. It runs the annual London Film Festival along with the London Lesbian and Gay Film Festival and the youth-orientated Future Film Festival. Due to their support of small independent film this could provide some opportunity for screening my film to help get it out there.
This is an example of a British film company that wouldn't be interested in my film and they tend to focus on "mid-Atlantic" Rom-coms that appeal to wider audiences in America to make more money.

Film 4 is probably the best known British independent film company. It owned and operated by Channel Four Television Corporation and has a history of distributing british films. They also screen independent british films on their tv channel.

Warp Films is an independent film company based in the UK. My film would have appeal to them or one of their sister companies and could provide the best chance of being a distributor of my film.
