While promoting the fifth installment of Die Hard, Willis let it slip to BBC's 'The One Show' that, even after shooting the movie, he never really got the title. “I don’t understand it. ‘It’s a Good Day to Die Hard’? No, I’m still working on it.” Judging on the box office numbers, it didn't really matter to anyone if the title made sense. In the end, it was just a good day to get paid.
