In her senior year at the Fashion Institute of Technology, Jillian decided to pursue acting instead of fashion. Her only acting experience was some drama classes in college, but she began looking for work in commercials and as TV show extras such as Law & Order and Blue Bloods. She was spotted by Joss Whedon as an extra in The Avengers, and offered a leading role in Whedon's "Much Ado About Nothing".
