The cinematographic relationship between Hollywood and Ireland is not a new subject in itself ; important films with an Irish background and produced by American studios have existed for a long time in Hollywood and among the most famous productions, one has just to remember The Quiet Man (John Ford, 1952) to conjure up memories of good quality entertainment. What the present paper aims at doing is focusing on a particular aspect of that relationship in the context of currently dominating American blockbusters at the box office. The paper is thus going to question the contemporary cinematographic relationship between Hollywood and Ireland from an economic point of view. In that perspective, it is first going to see the reasons why American film productions elected to go to Ireland. Then the paper is going to focus on the subsequent impact of that choice on Ireland, before it finally examines that relationship in the context of a currently globalised economy.
