Preview: A Good Day to Die Hard

When John McClane heads to Moscow, he doesn't expect to find out his son is a spy. But that's exactly what happens in the fifty installment of Die Hard. Jack McClane is a CIA operative, and he and dad end up working together to stop a man planning mass terror.

Bruce Willis will of course be returning in one of his iconic roles. Less well known Australian actor Jai Courtney will be joining him as Jack.

Mary Elizabeth Winstead is also returning to the series, continuing to play Lucy McClane, John's daughter. Her role is a little less clear, but she does seem to be doing a lot more helping this time, as the trailer shows her shooting a weapon.

A Good Day to Die Hard hits theaters on February 14. Yes, Valentines Day.
