Robert De Niro and Martin Scorsese were “scared” of her on the set of Taxi Driver.During a recent appearance on the US chat show Jimmy Kimmel Live, to promote the new season of True Detective, the two-time Oscar-winning actor reflected on her experiences from being a child actor, including her landmark role in Scorsese’s 1976 film.In Taxi Driver, Foster played the role of a child sex worker named Iris alongside De Niro, who starred as a lonely Vietnam veteran with mental health issues.“I was 12. And they had to say things like, you know, Can you pull his fly down?’ And it was a little awkward,” Foster recalled.Foster noted how, because she had been on more film sets than Scorsese and De Niro at that point in time, her elder colleagues were somewhat intimidated when having to interact with her.“Yeah, they were a little scared, Scorsese especially, who kept giggling every time he talked to me.
