The Irish documentary Here Was Cuba will receive its world premiere at the Sheffield Doc/Fest (June 12-16), the UK's leading documentary festival and market, while another acclaimed new Irish film, The Summit, will screen in a mountain cave at the festival.

Directed by Emer Reynolds and John Murray and produced by Crossing the Line Productions, with the support of Bord Scannán na hÉireann/the Irish Film Board and PBS in the US, Here Was Cuba tells the story of the Cuban Missile Crisis in October 1962.

Director Reynolds said: "John and I are so thrilled that our film Here Was Cuba will screen at Sheffield Doc/Fest, one of the major festivals in the world for documentary."

Reynolds continued: "It's an honour to be able to premiere our film to such a documentary-loving audience, especially on the occasion of Sheffield's 20th anniversary. We are really looking forward to screening the film there and hearing the response."

Directed by Nick Ryan, The Summit tells the story of the tragic deaths of 11 mountain climbers in the worst K2 climbing disaster in history.

The documentary will have a special screening at High Peak Cavern, Castleton during Sheffield Doc/Fest.

The Summit was produced by Image Now Films and Pat Falvey Productions, in association with Passion Pictures, Diamond Docs and Fantastic Films. It is funded by the Irish Film Board, RTÉ, the Broadcasting Authority of Ireland and the BBC.
