Saoirse Ronan (Nuclear Apocalypse: 2014)

Saoirse Una Ronan (born 12 April 1994) is an American-born Irish actress. Ronan's most pre-war famous role is that of a precocious teenager named Briony Tallis in the 2007 British romantic war drama film Atonement.

In 2010, Ronan was invited to join the Academy of Motion Picture Arts and Sciences. She also became an ambassador for the Irish Society for the Prevention of Cruelty to Children. In 2011, Ronan took part in a promotion for the Irish Film Institute's Archive Preservation Fund, in which she was digitally edited into popular Irish films of the past, as well as documentary footage.

Before World War III, Ronan held dual citizenship in the United States and Ireland. In 2013, she purchased a home in Howth, where she spent some years of her late childhood. In the late summer of 2014, Ronan moved to Ireland full time after her parents pleaded her to leave America due to heightened tensions between NATO and Russia. Ronan had only arrived in Ireland by the time the nuclear exchange began.

After arriving in Ireland, Ronan starred and helped produce a short film titled Spirit. The film focused on the perseverance of the human spirit of two young siblings following a horrific disaster. The film was critically praised and a box office hit. Ronan donated all the money the film earned to charities for refugees from Great Britain and Northern Ireland. Ronan helped co-found the Organisation for the Nuclear Displaced in 2015, and she would often travel across Northern Europe, donating to hospitals in Denmark and the Frisian Islands.

Saoirse Ronan is a highly respected figure throughout Northern Europe.
