NEW YORK — Martin Scorsese is developing a TV series based on his 2002 film “Gangs of New York.”

The director is partnering with Miramax, which released the Oscar-nominated film starring Leonardo DiCaprio and Daniel Day-Lewis. The planned show doesn’t yet have a TV network.

The series expands on the brutal, 19th-century New York gang world of the film. Miramax says the series will chronicle the birth of organized crime in not just New York but also in cities such as Chicago.

Scorsese says the era was too rich to fully explore in a two-hour film. He says the series “allows us the time and creative freedom to bring this colorful world, and all the implications it had and still does on our society, to life.”

Meanwhile, Scorsese wants New York’s mean streets to keep some of their grittiness.

The director has joined an effort to curb redevelopment of the Bowery. That’s the former skid row near where Scorsese grew up.

Scorsese wrote to the New York City Planning Commission recently and praised the neighborhood’s grittiness, ambience and vivid atmosphere.

He is backing a plan that would limit the height of new development on the east side of the Bowery to eight stories. The plan also calls for pre- serving several historic buildings.
