Who is the "movie star" being referred to in one of the scenes from The Social Network?

Question

In The Social Network, which "movie star" was Divya Narendra referring to when he says:

The biggest thing on a campus that included nineteen Nobel Laureates, fifteen Pultizer Prize Winners, two future Olympians, and a movie star.

Answer 1

I had always thought that referred to Natalie Portman who graduated from Harvard in 2003 around the time that The Social Network was to have taken place.

Out of the list on Wikipedia (which is certainly by no means authoritative or exhaustive), she's the only actor/actress that would fit that time frame.
