Screenplay Structure Analysis An exploratory data analysis of fourteen screenplays — eleven critically acclaimed films and three lower-rated comparison films. The central question: do great screenplays share a common structure, or only a common structural discipline? Films Analyzed Acclaimed Title Writer(s) Year Ikiru Hashimoto, Kurosawa, Oguni 1952 Thelma & Louise Callie Khouri 1991 Boogie Nights Paul Thomas Anderson 1997 Eyes Wide Shut Stanley Kubrick 1999 Moonlight Barry Jenkins 2016 Get Out Jordan Peele 2017 Parasite Bong Joon-ho & Han Jin-won 2019 Portrait of a Lady on Fire Céline Sciamma 2019 Aftersun Charlotte Wells 2022 Sentimental Value Joachim Trier & Eskil Vogt 2025 Sinners Ryan Coogler 2025 Comparison Title Writer(s) Year RT Score The Mummy Koepp, McQuarrie, Kussman 2017 24% Amsterdam David O.

Built by hand in both HTML and JSON, loaded and compared in R. Story beat sheet — six structural moments coded by hand for each screenplay: inciting incident, Act I break, midpoint, Act II break, climax, and resolution. All positions recorded as page numbers and converted to percentages of total script length for cross-film comparison. PDF extraction — dialogue exchange frequency and average lines per page extracted programmatically using pdftools and stringr. Four films were excluded from extraction-based metrics due to scanned PDFs with no extractable text. Visualizations Estimated act structure with act break positions Beat interval heatmap — where each screenplay spends its pages Climax to resolution length — post-climax runway by film Key Finding Structural timing alone does not explain quality. The comparison films hit broadly similar structural marks to the acclaimed films. What appears to differ is harder to quantify — the purposefulness of what happens between those marks. Great scripts in this sample share structural discipline more than structural uniformity. Tools R / RStudio — data loading, cleaning, extraction, analysis ggplot2 — all visualizations Quarto — final report, published to RPubs Packages pdftools # PDF text extraction stringr # string parsing rvest # loading HTML jsonlite # loading JSON tidyr # reshaping dplyr # data manipulation ggplot2 # visualization readr # CSV loading purrr # functional tools Notes Ikiru appears in the metadata and act structure analysis but is omitted from the beat interval heatmap and ending compression chart due to an unresolved Act II break that could not be coded with confidence. Four screenplays — Boogie Nights, Portrait of a Lady on Fire, Thelma & Louise, and one additional title — had PDF scan issues that made text extraction unreliable. Those values are recorded as NA and noted where relevant.
