escapes Pinbacker by ripping the skin off one of his arms. Cassie encourages Capa to ignite the bomb, and he manages to reach the controls. Unsure if it will work under these extreme conditions, he watches as the bomb begins to ignite at the edge of the Sun, killing Cassie and Pinbacker. As time and space distort, Capa uses his final moments to blissfully reach out and touch the surface of the Sun. On Earth, at the frozen Sydney Harbour, Capa's sister and her children listen to Capa's last transmission and witness the Sun's light starting to shine again. Cast Cillian Murphy as Robert Capa, the physicist who operates the massive stellar-bomb device. Murphy described the character of Capa as a silent outsider, which was due to the fact that only Capa understood the operation and true scale of the bomb. Murphy worked with physicist Brian Cox, who praised Murphy's performance as "brilliant" and a "great portrayal as a physicist," to learn about advanced physics, touring the CERN facility and learning to copy physicists' mannerisms. The actor also studied the thriller The Wages of Fear (1953) with Boyle to gain an understanding of the type of suspense that Boyle wanted to create in the film. Murphy said that his involvement in the film caused him to change his views on religion from agnosticism to atheism. Chris Evans as James Mace, the engineer. Evans described his character Mace as one with a military family and background. Mace has a dry and morally uncomplicated personality. Said Evans, "[He] has a very level head which enables him to operate fairly coherently under pressure-filled situations." Rose Byrne as Cassie, the space vessel's pilot. Byrne was chosen by the director for her role in Troy (2004). Byrne described Cassie as the most emotional member of the crew, "[wearing] her heart on her sleeve". Byrne considered Cassie's role among the crew was to possess an even temperament which helps her last the journey. Michelle Yeoh as Corazon, the biologist who takes care of the ship's "oxygen garden". Boyle cast Yeoh based on her performance in Tomorrow Never Dies (1997), and Memoirs of a Geisha (2005). Yeoh described her character as more spiritual, explaining Corazon's background, as an "Asian influence or that she's always constantly surrounded by organic things – she's very grounded and more down-to-earth." Cliff Curtis as Searle, the ship's doctor and psychological officer. He
