A Guns n’ Roses bio-pic about the band’s early days is in the works.

It’s based on Reckless Road, the book written by Slash‘s childhood friend Marc Cantor. In a series of posts on the GNR fan site MyGNRForum.com, Cantor confirmed rumors that the film was in the works and said it will feature “a few A-list people in the cast.” Cantor says he’s not making the movie himself but that “I do have a big say-so on the script, which is still being put together now, but so far looking cool.”

He adds, “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 dialog was between the band for many of the events that took place.”
