Who wrote 'An Inconvenient Study' and when was it published?
Executive summary
Reporting and promotional material identify Del Bigtree as the public face and driving force behind the documentary An Inconvenient Study, which premiered widely in October 2025; multiple outlets list the film’s first public screenings around October 12, 2025 and a nationwide release date of October 3 or similar October dates [1] [2] [3]. The documentary centers on an unpublished Henry Ford Health study led in reporting by Marcus/Mark Zervos (also shown as Marcus Zervos) and surfaced publicly in September–October 2025; available reporting describes the film as released in October 2025 rather than as a written work with a conventional author/publication date [4] [5] [1] [3].
1. Who is presented as the “author” or creator — the filmmaker and public promoter
Promotional pages and credits for the project identify Del Bigtree as the journalist who initiated and fronts the documentary An Inconvenient Study, and IMDb credits Kris Armstrong as the director while listing Del Bigtree prominently among the cast/figures featured [6] [1]. Press releases and distribution notes emphasize Bigtree and ICAN (Informed Consent Action Network) as central to the film’s launch and promotion [3] [6].
2. When was the film first published or widely released?
Multiple sources place the documentary’s public premiere and wide release in October 2025. IMDb and GlobeNewswire note an October release window — IMDb lists an October 12, 2025 premiere and a nationwide release cited as October 3, 2025 in plot details; GlobeNewswire and related press pieces report a global premiere on October 12, 2025 and distribution across October 2025 [1] [2] [3]. Promotional and news articles repeatedly reference “early October 2025” as when the film appeared publicly [7] [8].
3. What is the central work the film claims to expose, and who is named as its lead author?
Reporting about the documentary and the hearings it references names a retrospective vaccinated-versus-unvaccinated study, with Dr. Marcus (also reported as Mark) Zervos described as the lead author from Henry Ford Health; several outlets and commentary pieces discuss Zervos as the researcher connected to the study featured in the film [4] [5] [9]. Promotional materials for the film and allied organizations likewise refer to “the study” and present Dr. Zervos as central to the story [4] [6].
4. Was “An Inconvenient Study” released as a written article or traditional academic paper?
Available reporting consistently describes An Inconvenient Study as a documentary film, not as a peer-reviewed article or book; the debate in reporting concerns an unpublished Henry Ford Health research paper that the film claims was suppressed or rejected, while the documentary itself was released in October 2025 [1] [3] [10]. Michigan Public and other news outlets note that the underlying Henry Ford study “was never published” and remained out of the public eye prior to its appearance in hearings and the film [10].
5. Competing perspectives in the coverage about publication and credibility
The documentary and its promoters argue the Henry Ford study was suppressed because its findings were inconvenient; ICAN, Del Bigtree, and allied outlets frame the film as exposing censorship and lack of transparency [3] [6]. Henry Ford Health and mainstream outlets dispute that characterization: Henry Ford issued a cease-and-desist and said the research “did not meet… rigorous scientific standards,” and news outlets report reviewers at Henry Ford declined to advance the study toward publication for methodological reasons [1] [10]. Independent biostatisticians and outlets such as The Conversation and The Hindu republished analysis criticizing the study’s methods and describing biases—reporting that the study was “severely flawed” and noting issues like surveillance bias in the retrospective comparisons [7] [8].
6. Clear limits of available reporting and what is not found
Available sources do not present a conventional byline for “An Inconvenient Study” as a written work; they treat it as a film with director and featured figures rather than a single-author publication [1] [6]. Sources do not provide a single definitive “publication date” for a written piece titled “An Inconvenient Study” because the item in question is a documentary released in October 2025 and the underlying Henry Ford study that the film discusses remains unpublished in the scientific literature according to reporting [3] [10] [1].
Bottom line: If your question asks who “wrote” An Inconvenient Study in the sense of a written article, available reporting shows no such authored paper — the title refers to a documentary fronted by Del Bigtree (directed by Kris Armstrong) that premiered in October 2025 and spotlights an unpublished Henry Ford study led by Marcus/Mark Zervos [1] [6] [4] [3].
