The theatrical release of Xavier Gens’ post-apocalyptic thriller about New York high-rise tenants who flee to their basement during a nuclear attack will feature additional footage not seen in the SXSW or Fantasia screenings.

Lauren German, Michael Biehn and Milo Ventimiglia star alongside Courtney B Vance, Ashton Holmes and Rosanna Arquette.

“Fans of director Xavier Gens’ Frontier(s) will be pleased to know that once again he has pulled no punches, and has delivered a kick-ass film that will set the bar in extreme cinema,” Anchor Bay Film’s svp of brand marketing Jennifer Roberts said.

“We felt strongly that we needed to bring his full vision to the screen, and confident this is the version audiences will want to see.”
