The film's surrealist sequences have been compared to Jean Vigo's French classic "Zéro de conduite" (1933). Anderson acknowledged an influence, and described how he arranged a viewing of that film with his screenwriters, Sherwin and Howlett, at an early stage in production planning, though in his view the Vigo film's influence on "if..." was structural rather than merely cosmetic. "Seeing Vigo's film gave us the idea and also the confidence to proceed with the kind of scene-structure that we devised for the first part of the film particularly."
