National Geographic's new biographical drama miniseries A Small Light tells the real-life story of Miep Gies, who played a critical role in hiding Anne Frank and her family during the Nazi occupation in Amsterdam. We caught up with actress Billie Boullet, who stars alongside Bel Powley and Liev Schreiber in her role as Anne Frank, which she says she hopes allows audiences to relate to Frank in a way they have never before.
