lavish productions due to budgetary constraints" (22). Having been advised by the associate producer at Warner's, Henry Blanke, to makeae every shot count" (qtd. in Jameson 38), Huston worked hard to tighten the narrative. To Hal Wallis's memo about the opening sequence being a little slow, for instance, he responded by "shrinking all the pauses and speeding up all the action .. making Bogart quick and staccato and taking all the deliberateness out of his action" (qtd. in Behlmer 118). Idling, then, would have been incompatible with the fast-paced world of noir and with the parsimonious ethos of Warner Bros. Indeed, idling would appear antithetical to the entire Classic Hollywood mode of filmmaking, which preferred the relentless roll of action to distracting stillness. That mode, modeled on the linear continuity of the assembly line, operated with the speed and efficiency that Mussolini claimed for his railroad system. In fact, as Lynne Kirby has effectively argued, cinema's continuity impulse ran parallel to the forward impulsion of the railways.4 It was the arrival of a train at a station that caused cinema's earliest spectators, who feared the train's onward momentum, to rush out of the way. Within less than a decade, when momentum itself was becoming the norm, a railcar became the site of a great robbery and, in the process, established the standard for narrative filmmaking. For while the Lumieres' Arrival of a Train at a Station (1895) marked the beginning of the movies' long-running relationship with the railroad, it was Edwin S. Porter's film that discovered how cinematic narrative might parallel the railways' code of continuity. Having been fascinated with Georges Melies's "trick films," like A Trip to the Moon (1902), Porter intuited that "'a picture telling a story in continuity form might draw the customers back to the theaters"' and then set to work in that direction (qtd. in Musser 25).
