After tackling the life of Canadian folk artist Maud Lewis, Aisling Walsh is set to tell another tale based on a true story. Deadline reports that the “Maudie” filmmaker is in pre-production on “One Life,” a Holocaust drama inspired by British humanitarian Sir Nicholas Winton.

Penned by “The Danish Girl” scribe Lucinda Coxon and Nick Drake, the pic revisits Winton’s “unheralded endeavors on the eve of World War II,” which “saved the lives of more than 600 European refugee children who otherwise would have died in the Nazi death camps. His actions were relatively unknown for nearly fifty years until, aged 88, he found himself driven to publicly reveal the past with which he had never fully reconciled in order to remind the world of the need for tolerance and humanity,” the source details.

Anthony Hopkins and Johnny Flynn (“Emma.”) will portray Winton.

FilmNation Entertainment and Cross City Films have “pre-sold most international markets on Kindertransport drama ‘One Life’ at the recent TIFF virtual market, including a deal with Warner Bros in the UK,” Deadline details.

Walsh won a BAFTA TV Award for “Room at the Top.” She most recently directed BBC One’s TV film “Elizabeth Is Missing,” an adaptation of Emma Healey’s novel of the same name. Besides “Maudie,” her other features include “The Daisy Chain” and “Joyriders.”

In an interview with us, Walsh recalled that the worst advice she’s ever been given is, “You can’t do it.” She emphasized, “I came from a family who taught me that I could do anything I wanted if I believed in myself.”
