The feature film with the most co-writers is '50 Kisses', which was produced by the London Screenwriters' Festival (UK) and has 51 co-writers officially credited. The film premiered at the Genesis Cinema in London, UK, on 13 February 2014. '50 Kisses' was an initiative run by the London Screenwriters' Festival, which aimed to connect screenwriters with filmmakers. The premise was that anyone could submit an original 2 page script, provided that it took place on Valentine's Day and contained a kiss. The best 50 scripts, with the addition of 1 script written by their own writing team, were adapted and edited together to make the feature film '50 kisses'.
