This study is based on the representation of British public school life in Lindsay Anderson’s film “If…”, particularly in relation to the ideology and conventions governing public school as an institution which is supposed to provide a genuine education. Lindsay, the film director introduces a fictional construct of public school world while not real, it has much to say in a fictitious manner. Lindsay avoids the realistic for a condensing poetic force. This poetic expression can be the most expressive in speaking the truth and giving a voice to the unheard. “If….” lays bare the inherently political nature in British public school. The school basic tenet is to nurture political agenda that determine the role of power and ideology in the socio-historical construction of such institution.
