GG doesn’t really need to review such a prominent movie (particularly a movie that was based on a non-fiction book that hadn’t even been published when they were filming), but there are some points he’d like to make (aside from recommending both movie and book).
The movie focuses on one particular moment in time for the black women computers (yes, it was a job before it was a machine) of Langley around the time of the Mercury program. As such, the movie rearranges many of the events documented in the book into a shorter timeframe (for instance, Mary Jackson’s long hikes to the segregated bathroom in the early 50s-and her angry tirade leading her to work in the wind tunnel group-were transferred to Katherine Goble in 1961, who had in fact ignored the absence of a Colored bathroom in her building by simply using the nearest available women’s room). It also seems to amplify the racial tensions within Langley (especially with the supervisor of the white female computers and the flight engineering group) compared to the book’s broader view of Langley as more of a refuge from the Jim Crow Virginia these women lived in outside of work. These cinematic choices are not bad, and the movie does more or less convey the barriers the women faced and overcame. This does make the movie more coherent than the book, which probably needed a bit more development time, because the narrative thread in the text gets tangled from time to time. So it is a feel-good movie about the unjustly oppressed getting at least some justice based on a groundbreaking book that is long overdue.
GG’s point is that this is also a cautionary tale, and this is clearer in the book than the movie. The book (unlike the movie) addresses the educational barriers these women faced, both in being black and female in the south. By focusing on the few who had the combination of luck and skill to succeed, both the movie and book bury the fact that this means there were many others with less luck but, probably, equal skill whose contributions were never made because of discrimination. A point too rarely made is that discrimination not only hurts those discriminated against, but it denies the rest of society the contributions those victims could have made. And although the overt legal discrimination of the past is gone, the continued dearth of minority faces in science in general and in the earth sciences in particular suggests that some styles of discrimination remain. Because of that, we are poorer as a discipline.
