Alan Turing was a real historical figure, and the film depicts his crucial role in breaking the Enigma code during World War II. While the film captures his genius, it takes some dramatic liberties with his personality and personal life.

Joan Clarke was a real cryptanalyst who worked alongside Turing at Bletchley Park. The film portrays her contributions, but their relationship is somewhat fictionalized for dramatic purposes.

Commander Denniston was a real figure at Bletchley Park. The film presents him as more antagonistic towards Turing than he likely was in reality, creating a source of dramatic tension.

Hugh Alexander was a real cryptanalyst and chess champion. The film accurately portrays his role at Bletchley Park, though some aspects of his character are dramatized.

John Cairncross was a real spy who worked at Bletchley Park. The film depicts his role in leaking information to the Soviet Union, though the extent of his involvement and motivations are still debated.

The film portrays Turing as socially awkward and somewhat abrasive, which has some basis in historical accounts. However, it also exaggerates some of his eccentricities and downplays other aspects of his personality, creating a somewhat simplified picture.

The film provides a reasonable explanation of how the Enigma machine worked and the challenges it posed to codebreakers. While some technical details are simplified, the general principles are accurate.

The film dramatizes the process of breaking the Enigma code, condensing the timeline and focusing on Turing's individual contributions. While Turing played a crucial role, the codebreaking effort was a collaborative one, involving many individuals and teams.

The film portrays a somewhat adversarial relationship between Turing and his team initially, which is partly true. However, it also simplifies the dynamics and downplays the contributions of other codebreakers, particularly those of Hugh Alexander and others.

The film accurately portrays the extreme secrecy surrounding the codebreaking operations at Bletchley Park. The need to keep the codebreaking success secret to avoid alerting the Germans is a central theme and is historically accurate.

The film correctly emphasizes the significant impact of the codebreaking on the outcome of World War II. The ability to read German communications is believed to have shortened the war and saved countless lives.

The film accurately portrays Turing's homosexuality and the prejudice he faced, which ultimately led to his chemical castration. The film highlights the injustice of his treatment and its tragic consequences.

The film portrays the British government's attitude towards Turing and his work as somewhat ambivalent. While the government benefited from his codebreaking, it also persecuted him for his homosexuality. This complexity is touched upon but could have been explored further.

The film suggests that Turing's codebreaking machines were destroyed after the war to maintain secrecy. While some records were destroyed, it's unlikely that all of Turing's machines were destroyed completely. Some parts likely remained and were possibly reused.

The film largely omits the crucial role of Polish codebreakers in the early stages of breaking the Enigma code. The Poles' work in developing the 'bomba' machine was essential and predated Turing's work. This omission is a significant oversight.

The film depicts Turing's later life and the difficulties he faced due to his conviction for gross indecency. The portrayal of his struggles and eventual suicide is consistent with historical accounts.

The film accurately depicts the wartime atmosphere and the secrecy surrounding Bletchley Park. The importance of Bletchley Park as a codebreaking center is a key element of the historical narrative and is well-represented.

The film correctly identifies Hut 8 as the section at Bletchley Park responsible for breaking the Enigma code used by the German navy. This was a crucial part of the overall codebreaking effort.
