K.J. Yossman Sarah Michelle Gellar is the embodiment of late ‘90s teen dreams thanks to iconic roles in “Buffy the Vampire Slayer,” “Cruel Intentions” and “I Know What You Did Last Summer.” After a self-imposed hiatus she recently returned to television with “Wolf Pack,” a show from “Teen Wolf” showrunner Jeff Davis which again deals with the traumas of teenhood. This time, however, she plays an ass-kicking investigator with a mysterious past as well as taking on an executive producer role on the project. “I like scheduling and budgets and all that,” she tells Variety in Cannes, where Gellar is in town to pick up a well-deserved Canneseries Icon Award. (Gellar says she was also offered an opportunity to direct “Wolf Pack,” which she turned down).
