Mitchell's résumé includes guest roles on the Aussie television series "Rush" and "Offspring," along with appearances in the indie feature films The Joe Manifesto and 6 Plots (both 2012). She also serves as the host of "Toon Time," an Australian variety show that mixes classic Warner Bros. cartoons with live-action comedy segments.
In 2012, Mitchell joined the cast of the Netflix original horror series "Hemlock Grove," playing a Pennsylvania woman who believes she was impregnated by an angel.
Julianne Hough (Safe Haven) stars in this horror-thriller as a young bride-to-be who deliberately crashes her car off a deserted highway in an attempt to escape from a charming, predatory hitchhiker, played by Teddy Sears (Masters of Sex). When the plan backfires, trapping her in an overturned vehicle, she defends herself against a terrorizing psychopath—only to uncover a shocking truth that fuels her fight for survival.
