Mank
Scored from 539 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 2020s (7,930 peers).
Summary
In 1940s Hollywood, screenwriter Herman J. Mankiewicz works on the screenplay that will become Orson Welles' 'Citizen Kane.' Dictating from a secluded retreat while recovering from alcoholism, Mankiewicz recounts his unconventional career navigating 1930s studio politics, powerful moguls, and the creative chaos of Old Hollywood cinema.
David Fincher directed Mank, a drama, biography and history film from 2020. It is rated PG-13. The runtime is 131 minutes. It stars Gary Oldman, Amanda Seyfried and Lily Collins. It was made in the United States.
539 IMDb reviewers rate with enough spread for a personal baseline to be measured, and those are the ones the calibrated score reads; a separate, broader pool of 546 reviewers with at least two reviews each feeds the raw-average track. 7,929 other films from the 2020s form the cohort it is ranked inside. A second review pool sits behind it as well: 302 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately.
How the score was built
We compare the reviewers of this title against every other title those same people reviewed. Each review is scored relative to the reviewer's own baseline — a 7/10 from a hard grader sits well above their average, while a 7/10 from a generous grader sits below theirs. Every reviewer then counts the same, so the result is a calibrated consensus rather than a raw average.
- Global percentile
- Where Mank lands against every title we rank.
- In-cohort percentile
- The same comparison narrowed to its cohort — titles of the same format released in the same decade. A 1970s film is judged against 1970s films, not against last year's streaming series. Ranked against Films · 2020s (7,930 titles).
- AI-adjusted percentile
- The same reviewer-normalized score, corrected for how much confidence the sample supports: thin samples are pulled toward the corpus average. Each title keeps the share n / (n + 53) of its measured distance from the average, where n is its calibrated-reviewer count, and the result is ranked on the same scale as the global percentile.53 is the median sample size across everything we rank. Here n is 539.
