This collection consists of "cutting continuity" scripts for two science fiction film serials produced by Republic Pictures, Undersea Kingdom (1936), and Flying Disc Man From Mars (1950). Both serials had 12 episodes, the scripts for all of which are in the collection.

"Cutting continuity" scripts were not so much as screenplays in the traditional sense of the primary documents that are used to construct a film, as transcriptions of the final filmed product that were sent to the Production Code Administration (the self-regulating Hollywood agency that from 1934-1968 examined and judged movies for their content), to state censors, or to exhibitors.
