One Life is a 2023 biographical drama film directed by James Hawes. Based on the true story of British humanitarian Nicholas Winton, the film alternates between following Anthony Hopkins as a 79-year old Winton reminiscing on his past, and Johnny Flynn as a 29-year old Winton attempting to help groups of Jewish children in German-occupied Czechoslovakia to hide and flee in 1938–39, just before the beginning of World War II. Helena Bonham Carter, Lena Olin, Romola Garai, Alex Sharp and Jonathan Pryce co-star in supporting roles.

Sir Nicholas George Winton was a British stockbroker and humanitarian who helped to rescue Jewish children who were at risk of being murdered by Nazi Germany during the Holocaust. Born to German-Jewish parents who had immigrated to Britain at the beginning of the 20th century, Winton assisted in the rescue of 669 children, most of them Jewish, from Czechoslovakia on the eve of World War II. On a brief visit to Czechoslovakia, he helped compile a list of children needing rescue and, returning to Britain, he worked to fulfill the legal requirements of bringing the children to Britain and finding homes and sponsors for them. This operation was later known as the Czech Kindertransport.
