Mikhail Tukhachevsky
There are anachronisms in the film—for example, the trials of Mikhail Tukhachevsky (June 1937) and Nikolai Bukharin (March 1938) are depicted as occurring at the same time. Tukhachevsky and Timoshenko are shown as marshals of the Soviet Union at the same time, but Tukhachevsky was executed in June 1937 and Timoshenko was not made marshal until 1940.
