First of all, the title is misleading: the film is primarily focused on the life of Bertha Felicie Sophie von Suttner and not Alfred Nobel. The other major flaw was the excuse given for Alfred Nobel selling his patents for dynamite to arms trader and financier (Parisian Banque de la Seine) Basil Zaharoff (assuming they ever met in real life): that he was preyed upon by Zaharoff because he was a "lonely guy". In reality, he was a member of the very prominent and wealthy Swedish Nobel family. His father, Immanuel, founded a war supplies factory (Fonderies et Ateliers Mécaniques Nobel Fils) producing explosive sea mines for the Russians in the Crimean War, and his younger brother, Ludvig Immanuel Nobel, became a wealthy oil tycoon (Branobel). How could Alfred be the frail, unknowing pawn the film makes him out to be? In the movie we see Alfred Nobel demonstrating his dynamite to military personnel. Then it shows Zaharoff convincing him that if it is sold to them then world peace will be had through the deterrent of "mutual assured destruction". How can we honestly believe that such an intelligent man could be so naive? The movie is preachy and the acting is terrible. I would suggest another source if you really want to learn something about Alfred Nobel and the Nobel Family. His "invention" made Alfred Nobel a multimillionaire.
A special note: The Nobel Prize for economics is actually given by the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel. This "privilege" of using the Nobel name began in 1968, when the Swedish Central Bank (Sveriges Riksbank) began making annual endowment payments "in perpetuity" to the Nobel Foundation.
This movie seems more like a deflective propaganda piece riding on the back of a pacifist (Bertha Felicie Sophie von Suttner).
