Julia Roberts: Cunt; Natalie Portman: 'Lil Cunt
From an interview in the July 2004 Interview Magazine between Peter Sarsgaard and Natalie Portman:
Peter Sarsgaard: Your character's (in Closer) deliciously foul mouth is ... memorable. (Portman laughs)
Natalie Portman: Very true. Julia Roberts plays the role of Anna, and we were laughing about the dirty words we have to say. You blush at first, and then you get pretty liberal with them.
Peter: There's nothing more fun than watching someone who's not quite comfortable with it really landing a well placed "fuck."
Natalie: Yeah, at the start of shooting I gave Julia a necklace that said 'Cunt' on it (laughs), then as a wrap gift she gave me one that said 'Lil Cunt.'"
