Ben Stiller came to upstate New York with several of the principle actors to finish work on the film "Escape At Dannemora." This will be an eight-part Showtime mini-series. The series is based on the real-life 2015 prison escape by convicted killers Richard Matt and David Sweat from Clinton Correctional Facility in Dannemora.

They were assisted by prison worker Joyce Mitchell, who got cold feet at the last minute and never showed up with the getaway car, leading to a 20-day manhunt throughout the Adirondack Mountains.
