We can't get enough of Dame Maggie Smith this week. For one, the accomplished British actress stars in the highly-anticipated "The Second Best Exotic Marigold Hotel," which opens this Friday. She also made headlines when she revealed to The Sunday Times that she's likely to leave "Downton Abbey" after next season. Ah, Dowager Countess, we will miss you...

Smith has had such a versatile career, wowing audiences in everything form Shakespeare to "Harry Potter" to "The First Wives Club," so we thought today's #TBT should be all about the Dame through the years. Flip through photos of Maggie Smith from the beginning of her career to now.
