Interstellar does not feature a large main cast. Aside from the male and female leads, there is the male lead's daughter as an adult, the elderly version of the daughter, the female lead's father, and the character played by Matt Damon.
Among them, the male lead's adult daughter and the female lead's father have slightly larger roles, qualifying as a supporting actress and supporting actor respectively, while the character played by Matt Damon is somewhat of a cameo.
After casting Liu Ye and Fan Xiaopang as the male and female leads, Liu Zhou quickly found suitable actors for the remaining roles.
