Pale-skinned nubile hottie Michelle Trachtenberg along with “The Office” Michael Scott concubine Melora Hardin have joined the cast of the “reverse BIG” comedy 17. The Burr Steers directed film stars Matthew Perry as a guy who wakes up 17 again (in the form of current tween dreamboat Zac Efron) and becomes involved in all kinds of hijinks-filled hilarity. Leslie Mann had previously signed on as Perry’s wife. Trachtenberg will play Perry’s daughter who finds herself crushing on her 17 year old dad (Note: ewww). Hardin will play the principal of the school. Trachtenberg can next be seen alongside Topher Grace in the drama KIDS IN AMERICA. Hardin can still be seen giving Michael Scott the sex on “The Office” and can be seen alongside Katherine “I like to shit on movies that made me an A-list star” Heigl in the upcoming romantic comedy 27 DRESSES.
