The 32-year-old actor said he is looking forward to portraying the heroic figure, reported OK magazine.
"I look at Capa's life and see it in heroic terms. A Hungarian kicked out of Hungary for writing against Fascism, he moved to Germany where he was kicked out for being Jewish, then he moved to France and from there began a life-long commitment to make a stand against forces of fascism," Hiddleston said.
The film will begin in Paris 1935, capturing the moment where two exiled Jewish Communists, Gerta Phorylle and Endre Friedmann, start a relationship and change their names to Gerda Taro and Robert Capa in order to sell their photographs.
Hiddleston can next be seen as villain Loki in 'Thor: The Dark World'.
