Book excerpt: This study is the first of its kind to analyse the representation of Irish English in film. Using a corpus of 50 films, ranging from John Ford's The Informer (1935) to Lenny Abrahamson's Garage (2007), the author examines the extent to which Irish English grammatical, discourse and lexical features are present in the films and provides a qualitative analysis of the accents in these works. The authenticity of the language is called into question and discussed in relation to the phenomenon of the Stage Irishman.
