Katie Finneran

Though a celebrated and Tony-winning performer on Broadway, actress Katie Finneran did not receive her breakout role on television until 2013, some two decades after her small screen debut, when she was cast as Michael J. Fox's sister on "The Michael J. Fox Show" (NBC 2013-14). Finneran's professional career began in the early '90s, and while she advanced quickly from supporting performances on stage in "My Favorite Year" (1992) to a Tony-winning performance in the comedy "Noises Off" (2002), her screen performances were relegated to guest roles in features and on television in several failed series, including the critically praised "Wonderfalls" (Fox 2004). She claimed a second Tony in 2010 for a knockout performance in a revival of "Promises, Promises," which served as the launching point for her profile's rapid ascent: steady work on TV led to another hit musical, a 2012 revival of "Annie," which she departed to star on "The Michael J. Fox Show." Finneran's brassy, unfiltered turn on the series won her greater acclaim than the show itself enjoyed, and indicated that her many years in relative obscurity as a TV talent had finally paid off with stardom.
