Bruce Willis fears being replaced in `Die Hard 6`

London: Hollywood actor Bruce Willis, who is currently filming his fifth film, says he is concerned that he may be replaced in the `Die Hard` franchise.

"In the next few years they could easily find a replacement for me or call the character someone else. But for me, 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," quoted him as saying.

"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."
