Kurt Russell says the whole ending of Fast and Furious 7 is being changed in the wake of Paul Walker's death.

The film franchise's star was killed in a horrific accident on November 30 when the car Paul was traveling in careered off the road and smashed, which has led to his final film - which was incomplete at the time - being significantly altered.

"They're having to rewrite, they're having to do whatever they're having to do to deal with the situation. Listen, it's catastrophic. It's the worst thing that could happen to a movie, but it's not as bad as what happened to Paul. So everything is in perspective. He was a terrific guy. And life is full of curveballs," Kurt - who is joining the franchise playing a father figure to Vin Diesel's character - told ETonline.com.

The 62-year-old star added the fate of his own character may now change in the new ending. "Whether or not this guy dies off in the movie, we don't know, and that may have changed now significantly, too," he added.

It has previously been claimed Paul's character - undercover police officer Brian O'Connor - will not be killed off in the movie and will instead be written out of the script using existing footage of Paul in a bid to keep fans satisfied and allow for the franchise to continue in future.
