The increased populist and punitive turn in criminal justice policy in the United Kingdom over recent years has led to punishment becoming politicised, harsher and more ostentatious. The role of media and popular culture discourses of prison is rarely examined in this account. Adopting a Foucauldian discourse analysis of prison films released over the past 10 years, this article explores the prison film as one important element of the discursive regime. It seeks to investigate what representational practices are at work, how they limit the meaning of prison and prisoners, and how this may contribute to debates about the nature and aim of prison in contemporary society. It argues that several discursive practices exist in cinematic representations of the incarceration that strengthen support for the use of prison. The explicit and recurring depiction of violence in most prison films over the past 10 years, while appearing to offer evidence for prison reform, does the opposite. This paper suggests that discourses around the futility and inhumanity of incarceration are scant, replaced by scenes of prison violence; rape and death appear, which appear to exist purely for the pleasure of the spectator: a generic feature of the prison film. Secondly, prisoners are largely constructed as an inhuman other: a danger to society and deserving of harsh punishment. Consequently, the discursive regime of prison in cinema over the past decade constructs prison as not only necessary, but as the only process for crime control and reduction.
