Jodie Foster, who has applied the brake pedal to her career since giving birth to her son Charlie 18 months ago, says she has finally achieved her “finest ambition.” That is, “to be the most boring person on Earth.” The star, whose new movie is “Anna and the King,” told the Ladies’ Home Journal that having a child has enabled her to see “all the crappy things you do that you have to stop doing.” She also launches a broadside at those of her colleagues who overextend themselves. “Because they’re always sitting in the star chair,” she says, “they don’t have time to be the other person who does the old stuff, like going shopping and getting food on the table.”
