It sounds like fun and games  the boozy, all-woman answer to those close-knit gangs of Hollywood boy-men captured on screen in “Entourage” and embodied by the real-life Apatown, the industry moniker for filmmaker Judd Apatow’s coterie of actors and screenwriters including Paul Rudd, Jason Segel and Seth Rogen. But these women also work hard: Ms. Cody, Ms. Fox and Ms. Scafaria can command seven figures to write a movie that makes it into theaters with big stars. Ms. Meriwether (the others call her “the freshman”) is on her way to joining them. That’s no small achievement when you consider that among the screenwriters who are in steady demand for major projects, only about 20 are women. Don’t even try to credit their bankability to their looks.

“When you read a screenplay, it doesn’t come with a picture on the cover,” said Adam Siegel, president of Marc Platt Productions, a producer who is friends with all four women and has worked with all except Ms. Cody. “I know a few beautiful women, but none of them write like Dana, Liz, Lorene or Diablo.”

But not everyone loves these four women, and plenty are happy to say so (many of them anonymously). So among them there is also a battle-scarred camaraderie. “Whenever you have a project out in wide release, there are haters,” Ms. Cody said. “Blogs, imdb, Rotten Tomatoes, reviews. It’s a lot to deal with. When most people get Googled, they get maybe a Facebook page. When we get Googled, there’s criticism, bad reviews, commentary on the way we look. You need people who have been through it.”

The Fempire’s solid front  all four wear the same gold necklaces with tiny heart pendants inscribed with words that can’t be printed here, gifts from Ms. Cody  seems to make some men nervous and envious at the same time.

“I adore them and I’m terrified of them,” said Jason Reitman, who directed “Juno.” “There’s so much talent packed in the group. Writing is such a solitary activity. The idea that they have each other is quite lovely. When I think of the four of them together, writing, of course I’m jealous.”
