Bruce Willis stars in Have a Sandwich and Let's Go Shopping - Then Die Hard. Because that makes as much sense to him as the title of his latest film, A Good Day to Die Hard.

In a very awkward interview on UK TV today, Willis appears reluctant to promote the film, offering one word, mumbled answers to questions and a shrug of the shoulders to clips of his character shooting up the screen.

Perhaps endless publicity tours for the Die Hard films have made him jaded - there is, after all, only so much you can say about a shabby cop who inexplicably finds himself saving the day from bad guys hell-bent on destroying skyscrapers, airports, New York and the internet.

Hilariously, the one topic that does get Willis animated during his appearance on BBC's One Show is the film's title.

Cutting off a stream of toadying praise from host Matt Baker, he says: "Let me ask you guys, what about the title? Are you confused by it?"

Co-host Alex Jones admits she did think the name was strange, to which Willis responds: "I don't understand it. It's a Good Day to Die Hard? No, I'm still working on it.

"It's a difficult title. It's A Good Day... To... Die...eee..."

Jones tries to roll with Willis's oddness and chips in: "I suppose it's because you had kind of a good day, and if you would have died then so be it. Is that it?"

Willis isn't convinced though: "That's it, have a sandwich and let's go shopping - then die hard."

Frustrated, Baker then asks: "Would that have been your chosen title?"

Willis: "It makes about as much sense."

The other Die Hard titles explained for Willis.

Die Hard - Willis plays an old fashioned New York cop who not only stubbornly resists change and clings onto seemingly hopeless or outdated causes but he's also hard to kill.

Die Hard 2: Die Harder - Willis' cop is back for a second helping. The stakes are higher so the dying will be harder.

Die Hard with a Vengeance - The brother of the head bad guy killed in the first film wants revenge. Dictionary time, Bruce: Vengeance is the act of taking revenge.

Die Hard 4.0 - The film is about the web. Surely even you've heard about the web, Bruce?

A Good Day to Die Hard hits New Zealand cinemas on February 14.
