Someone spray-painted "Do the Right Thing" on the brownstone in the Fort Greene section next to Lee's family home Friday.
That's the title of one of Lee's best-known movies.
The Lee family house had part of the title written on the side of the stoop.
The vandalism happened three days after Lee criticized gentrification of the black, working-class neighborhood during a Black History Month speech.
Lee's half brother Arnold, who lives in the house that was hit by vandals, told the Daily News of New York (http://nydn.us/OKlgJ3 ) that Lee "needs to stop mentioning the house in his comments."
