Willis, 55, has played the role of John McClane in the first four movies that have been released between 1988 and 2007.
He recently revealed the script for a fifth movie is almost done and said he will reprise the role for the next two movies.
Willis told Britain's FHM magazine: 'I want to do Die Hard 5, then one final Die Hard movie - Die Hard 6 - before finally hanging that white vest up for good.
'At the moment, I can run and I can fight on screen. But there will come a time when I no longer want to do that. That's when I'll step away from the Die Hard films.'
