She looks like a young Jodie Foster.

Funny you should mention that. Jodie Foster had a similar role in "Taxi Driver" to the one Fanning is about to play.

In the more explicit scenes in TD Jodie Foster's older sister acted as a body double.

"Jodie Foster had a similar role in "Taxi Driver" to the one Fanning is about to play."

Yep, you're right on the money....

Dakota Fanning born Feb. 23, 1994 = 12 years old in 2006

Jodie Foster born Nov. 19, 1962 = 12 years old (when "Taxi Driver" was filmed, Summer 1975).

Foster was a much more mature 12 year old, though.
