Critical Whiteness studies has emerged as an academic discipline that has produced a lot of work and garnered attention in the last two decades. Central to this project is the idea that if the processes of Whiteness can be uncovered, then they can be reasoned with and overcome, through rationale dialogue. This article will argue, however, that Whiteness is a process rooted in the social structure, one that induces a form of psychosis framed by its irrationality, which is beyond any rational engagement. Drawing on a critical discourse analysis of the two only British big budget movies about transatlantic slavery, Amazing Grace and Belle, the article argues that such films serve as the celluloid hallucinations that reinforce the psychosis of Whiteness. The features of this discourse that arose from the analysis included the lack of Black agency, distancing Britain from the horrors of slavery, and downplaying the role of racism.
