This documentary combines archive footage and acted scenes to show parts of Albert Einstein's life and thinking, using his own words. This is the part I liked most about this film: in the acted scenes and the voice-overs, exclusively verbatim quotes by Einstein are being used. No invented dramatizations. The documentary does a good job in using Einstein's quotes to show his beautiful and exceptionally intelligent mind and to paint a coherent image of the his pacifist and internationalist convictions.
However, you might be disappointed if you are expecting more insights into Einstein's connection to the development of the atomic bomb. Contrary to what the title promises, there is very little content on that matter, beyond a reference to the Einstein-Szilard letter, his motives for signing said letter and his posterior regrets. Actually, only the last third of the film even touches upon these questions. For the larger part, it shows Einstein's life in the 20s and 30s, interlaced with the rise of the Nazis and World War II. It does not contain more insights on the development of the atomic bomb and Manhattan Project than does Oppenheimer and it does not show his private life in the way season 1 of Genius does.
The acted scenes mostly take part in Roughton, Norfolk, where Einstein was offered refuge in September 1933 by MP Oliver Locker-Lampson after fleeing Germany. The reason for focusing on that relatively minor episode of his life may be that this is a British production which wished to highlight the one relevant connection of Einstein with the UK.
In some scenes, Einstein seems oddly mute, which presumably has to do with the decision to only use documented quotes, so no small talk is possible. As in other documentaries, such as in Genius, the producers (annoyingly) decided to let the acted Einstein speak only English (with German accent), even when he speaks to other Germans, rather than have him also speak his native German language.
The film ends on a strong note, with two message to us contemporary viewers. "The fate of mankind hinges entirely on man's moral development." - "Dear posterity, if you have not become more just or peaceful and generally more rational than we are or were, then may the devil take you."
