According to Collider, it’s been confirmed that A Good Day to Die Hard (AKA Die Hard 5) will be rated R.
Plot is as follows:
Iconoclastic, take-no-prisoners cop John McClane (Bruce Willis), for the first time, finds himself on foreign soil after traveling to Moscow to help his wayward son Jack–unaware that Jack (Jai Courtney) is really a highly-trained CIA operative out to stop a nuclear weapons heist. With the Russian underworld in pursuit, and battling a countdown to war, the two McClanes discover that their opposing methods make them unstoppable heroes
The previous DH film, 2007’s Live Free or Die Hard which had Mary in the role of Lucy McClane, was rated PG-13.
