Happy birthday, Elizabeth McGovern! The actress, best known for her role in Downton Abbey, turns 53 today. Making her big screen debut in 1980s Ordinary People playing the girlfriend of troubled teen Timothy Hutton, she went on to be nominated the following year for her performance in Ragtime and has since starred in countless films and TV shows. The timeless beauty’s career spans close to 40 years, and shows no signs of slowing down—she is currently filming Woman in Gold, a drama that also boasts cast members, Helen Mirren, Ryan Reynolds, and Tatiana Maslany.
