Jessica Brown Findlay
Like many of her co-stars on "Downton Abbey" (ITV/PBS, 2010-16), British actress Jessica Brown Findlay, who played the socially conscious Lady Sybil Crawley on the series, was elevated from relative obscurity to worldwide fame with the groundswell of popularity that rose around the show's debut. She was also able to parlay that attention into a successful film career, beginning in 2011 with her starring turn in the critically acclaimed independent film "Albatross." Featured roles in U.K. television productions soon led to major roles in American projects like the drama "Lullaby" (2013) and the female lead in the all-star fantasy "Winter's Tale" (2013). Findlay's ascent from British television player to Hollywood film actor on the strength of both the international popularity of "Downton Abbey" and her own undeniable talent underscored her status as a major star on the rise.
