25 years after the first Die Hard film was made, Bruce Willis struts down the red carpet for the 5th instalment of the action franchise, A Good Day To Die Hard. And he's not done yet. 

On a rainy red carpet in London's Leicester Square last night (Thurs Feb, 7) Willis said to The Huffington Post: "I seldom think about the passage of time. I'm always surprised to hear that it's been 25 years. It's still fun to do." And at the age of 57, he admitted that the early starts and long hours don't put him off. "I still like making movies. They're fun to do, especially these Die Hard films," explained Bruce. So will we be seeing a sixth Die Hard movie? It would appear Willis isn't ruling anything out. Die Hard 5 sees John McClane team up with his son, Jack, to fight off the terrorists. 

Australian actor Jai Courtney - who plays McClane Junior - says the experience was "fun" but "surreal" at times. "Bruce is a lovely guy. We had a lot of fun making the movie. It was surreal and kind of strange but a lot of fun," he said. "You need a lot of trust too and we were able to work together in an organic fashion and had a lot of fun in the process. There was a lot of chemistry there," added Courtney.
