Bel Powley stars in the trailer for Ashes in the Snow, a film adaptation of Ruta Sepetys' novel Between Shades of Gray. Powley has been acting for more than a decade now, but it was her role in 2015's The Diary of a Teenage Girl that really put her name on the map stateside. The film revolved around a teen artist growing up in San Francisco circa the 1970s, and landed Powley multiple film festival and critic circle award nominations for her performance. She's since gone to appear in films like the biopic Mary Shelly and this year's White Boy Rick, in addition to her role in Ashes in the Snow.
