evidence: The film features an all-star ensemble cast led by Cillian Murphy as the US physicist, J Robert Oppenheimer. [...] He added: "Playing Oppenheimer from his early 20s to late 50s, the 47-year-old Murphy gives the performance of his life, imbuing Oppenheimer's body with an enthralling nervous eroticism and his voice with a noirish musicality that reminds you of [Humphrey] Bogart." [...] He described Murphy as "an eerily close lookalike for Oppenheimer... very good at capturing his sense of solitude and emotional imprisonment".
