Good morning.

Today’s introduction is by Brooks Barnes, our Hollywood reporter based in Los Angeles.

Oprah Winfrey, Reese Witherspoon, Natalie Portman and more than a dozen other powerful Hollywood women have decided that sexual harassment in the entertainment business will continue unless a cross-industry action plan is created and executed. And they have privately — very privately — started meeting to get it done.

The fledgling effort was prompted by the torrent of allegations of sexual harassment against the producer Harvey Weinstein and first revealed in a subscription newsletter for Hollywood insiders called the Ankler. Details were confirmed by three women involved, who spoke on the condition of anonymity because the cadre has been trying to keep its existence a secret.

The group, which also includes the TV producer Shonda Rhimes, the “Spider-Man: Homecoming” producer Amy Pascal and the “Star Wars” producer Kathleen Kennedy, has held at least two meetings at Creative Artists Agency in recent weeks. As participants brainstorm solutions — insisting that entertainment companies hire more women, setting up an effective abuse reporting system — an informal battle cry has emerged: “Time’s up.”
