Among the homes of Rockland County, just north of Manhattan, is a farmhouse that has been featured in over 1,800 films, TV shows, and commercials. Douglas House has its reputation not only for being a sprawling, picturesque set but, by design, is built to facilitate easy and efficient production. And at the age of 91, Marjorie Douglas, the home’s owner, has hosted film and television crews about once a week for 36 years.
