David Mamet Rolls In His Grave* Crying, “Oy, Where Are The Adults These Days?”

Broadway producers look for that lucrative tween market, which obviously has more cash than it knows what to do with:

For Broadway producers, 10-year-old Jamie Carroll looks like an ideal theatergoer: she downloads scores off of iTunes, is a fervent proselytizer when she likes something and has lots of friends, two of whom she brought along to a recent Saturday matinee of “Legally Blonde.” “A lot of my friends say it’s the best musical they’ve ever seen,” she said.

Maybe. But Jamie’s father and her 14-year-old brother would not join them, considering the show too girly. Even her mother, Tacey Carroll, was only present as a chaperon: “This is a little more for them,” she said, echoing several other mothers at the theater, one of whom even dropped off her young charges and went shopping.

And that’s the rub for Broadway producers, for whom teenage and tween girls have become the demographic of the moment, wooed by marketing campaigns and featured as central characters in a flurry of shows in development, including “13,” about a teenager from New York who is transplanted to Indiana; “Princesses,” which is basically “High School Musical” meets “Gossip Girl”; and a musical adaptation of the movie “Clueless.”

Increasingly, though, some worry that the sugar-and-spice enthusiasm may be misplaced, because while teenagers and tweens may be helpful in creating a hit, they are far from enough to ensure one. For that, you still need grown-ups — lots of paying grown-ups — to want to come to a show.

*Just kidding, Mr. Mamet! We can’t wait for that Duran Duran thing to end to see your next play staged!
