WASHINGTON — OK, roll ’em!

The National Parks Service yesterday approved construction plans for the city’s first outdoor movie lot at Astoria-Kaufman Studios in Queens.

Federal red tape threatened to delay the $2 million project that is expected to open by the summer of 2013 and will help attract even more film projects to the city.

“We finally say ‘Action!’ ” said Sen. Chuck Schumer (D-NY), who had urged the agency to act.

“With the National Parks Service sign-off, the project can move forward on schedule and begin competing for major productions with places like Los Angeles and Toronto.”

The studio, which was turned over to the city decades ago, is also a national historic site.
