Kristen Stewart
In Panic Room (2002), Kristen Stewart stars in one of her earliest roles alongside Jodie Foster as a mother-daughter duo under attack. She was only twelve years old at the time. "I remember her thinking there wasn't a chance I'd continue being an actor," Stewart said of Foster. "[Jodie] was like, 'You're probably going to direct movies or go back to school."
Rooney Mara
The Carol actress might be a big star nowadays, but back in 2005, Rooney Mara was only known as Kate Mara's little sister. Mara earned her first IMDb credit while visiting her sister on the set of Urban Legends: Bloody Mary (2005), in which the vengeful spirit of a dead student terrorizes her peers on prom night. Mara played "Classroom Girl #1."
