Abstract: Film, Francesco Casetti argues, provided a common “field of convergence for different dimensions” of the popular imagination in the early twentieth century. We can see evidence of the extent of that “convergence” in the sort of discourse that unfolded in various other internal features of the pulps. Editorials, readers’ letters, and film reviews converge to demonstrate a sense of enthusiasm about the ability of films to supplement the work of SF by visualizing or realizing the genre’s ideas for reshaping the world and the self. That enthusiasm would bring repeated calls for the film industry to produce more SF-themed films, even to adapt favorite stories from the pulps. But as reviews of SF films began to proliferate in the pulps, particularly in the late 1930s, they would increasingly attest to a frustration or dissatisfaction with the sense of reality that was being achieved by the SF film and point to a rift beginning between the films and the world of SF literature.
