The film rights have been through multiple hands, and films in development have blown up at least twice in the last few years. A version starring Gerard Butler fell apart back in 2007 (see "'Escape from New York' Stalls"), and a version to be produced by Joel Silver was in development as recent as 2013 (see "Say It Isn't So Dept.:" 'Escape from New York' Trilogy").
The property’s still active in other parts of geek culture, though; BOOM! has a comic (see "'Escape from New York' Comic").
