A biography about the making of GUNS N' ROSES' debut album, Appetite For Destruction, is set to be adapted into a film.

Author Marc Canter, who wrote Reckless Road: Guns N' Roses And The Making Of Appetite For Destruction in 2008, has revealed a screenplay is currently in the works.

He says, "I do have a big say-so on the script, which is still being put together now, but so far looking cool. I am going to see that everyone in the cast is doing their job and doing justice to the band. Since I was there, I know what the dialogue was between the band for many of the events that took place."

Canter would not discuss who is involved with the movie, but assures fans it will be authentic.

He continues, "When you find out who is making the movie, you will then understand that it will be very cool. I'm proud of all the hard work that was put into this project and it's just going to kick a**.

"No one has been cast at this point but I would expect to see a few A-list people in the cast. (We're) just working on (putting together) the perfect script. Then they will move on to the next step, and yes, it will bring in a whole new slew of fans and sell a s**tload of records for the band. Also the band will do well on the music used for the movie."

While Canter insists he's happy with the way the project is shaping up, he admits frontman Axl Rose has not given the film his blessing.

He adds, "Axl doesn't support anything to do with the old band except playing their songs live. However, I do think he will be happy with the fact that it will clear up some stories that have been said about him from those days that were told incompletely. So setting the record straight on some of those evens will be a good thing for him to see happen.

"Axl should know by now that I have his back and that it will be done right. If I'm involved in a Guns N' Roses project, then you know I have their backs. There is a great story about the birth of the band which I was very much involved in. This has nothing to do with where the band is today. The history is very important and that's why Axl was the one who was most supportive of me documenting what they were doing when they first started out."
