Forbes has named Natalie the “best actor for the buck” in a new feature.

The calculation is based on the last 3 starring films (that opened in more than 2000 theatres) for actors, with Natalie’s films being No Strings Attached, Black Swan and Your Highness. They didn’t count Thor because Natalie was only supporting, even though she probably has more screen time in that film than Your Highness.

Even with that strangeness, the list is a lot of bunk. You can’t make such a determination of such a small sample size. It shows that Natalie had a couple very nice hits but I wouldn’t look much further than that.

We estimate that for every dollar Portman is paid by the studios, she returns $42.70. Compare that to Eddie Murphy, our most overpaid star, who returns $2.30 for every dollar he gets paid.

Out of interest, Kirsten Stewart was second and Shia LaBeouf third.
