It’s probably not a stretch to imagine that few people are interested in watching a movie about cryptography. Cryptography isn’t exactly a sexy topic in pop culture, but then again almost every element of World War 2 except cryptography has its own movie. This is somewhat ironic given the huge number of movies set in World War 2 and the incredible importance of cryptography during the war. Enigma is an attempt at a cryptography movie set in World War 2, and I had the opportunity of watching it this past weekend.

Engima is a mixed bag of incredible accuracy and complete fantasy. Perhaps the best example of this is the setting. Although Enigma is set in Bletchley Park, which is where Enigma was actually broken during the war, they don’t even use the actual Bletchley Park Mansion in the film. Almost the entire plot is fictional, but the details about the Enigma machines themselves are extremely accurate. There are a couple of scenes that quickly explain the purpose, construction, and use of the Enigma machines in a concise and easily understandable manner. If you’ve ever tried to do this, you probably know that isn’t easy. The depictions of the huts, bombe, and other elements of Bletchley Park were similarly well done. For example, the windows were shuttered at night to ensure that Bletchley Park wasn’t visible to the Germans from the air. The movie uses this during an excellent depiction of an all-nighter at Bletchley Park.

The main character, Tom Jericho, is based on a real person, Alan Turing. In the movie Tom’s life is turned upside down by a romantic relationship with a Claire, who disappears without a trace. Tom spends most of the movie trying to figure out what happened to Claire, and he ends up falling in love with his primary collaborator in the search. I hesitate to give away much more than that because the movie is primarily a mystery involving spies, codes, and secret love. It’s a fun little movie if you like guessing at what really happened.

Tom’s real-life counterpart, Alan Turing, proposed to Joan Clarke while at Bletchley Park despite being a homosexual. Turing was also famously eccentric. For example, he was an avid runner, but he would sprint anywhere he needed to be regardless of the distance or circumstances. He even ran the 40 miles to London from time to time. As you might imagine, this doesn’t always create a socially pleasant appearance. Alan spent the rest of his (short) life struggling with society’s treatment of his homosexuality. He committed suicide at age 41 in a strange and ambiguous fashion that might best be described in film.

Although I really enjoyed Enigma, it mostly left me thinking that someone desperately needs to make a movie about what really happened at Bletchley Park. So much has basically been forgotten or overlooked simply because it is so hard to describe to folks who aren’t mathematically inclined. There’s a common cliché in science fiction films where a geeky guy does some indescribably hard fictional math and saves the day. This usually occupies a tiny slice of the films in between insane computer generated fight scenes. This cliché applies to World War 2 films with two important exceptions. First, the cryptographers at Bletchley Park actually solved some incredibly hard problems. Like, it really, truly happened, and it actually saved the day. Second, World War 2 movies usually don’t even give Bletchley Park a tiny slice of the film in between computer generated fight scenes! As a result, pop culture is ignorant of one of the greatest stories of World War 2.

In short, if you’re interested in a fun, fictional mystery or if you enjoy cryptography at all, then Enigma is for you. However, if you’re looking for a movie that will accurately represent the reality of Bletchley Park’s role in World War 2, then you’re going to have to make it yourself. I recommend starting with some sort of combination of A Beautiful Mind and Saving Private Ryan.
