A biopic about the final days of late Soundgarden singer/guitarist Chris Cornell is reportedly in the works with production scheduled to begin as early as next month.

A report shared by Spin on Monday notes that a feature-length film based on the last days of Cornell’s life prior to his suicide in May 2017 will begin filming on September 10th. AmeriFilms LLC/Road Rage Films will produce the film, which is already in the beginning stages of pre-production. According to the film’s website, the project, currently titled Black Days, comes “from the cast of the Academy Award-winning ‘Walk the Line,'” John Holiday, who played the role of Carl Perkins in the Oscar-nominated 2005 Johnny Cash biopic, Walk the Line, is also referenced on the website, leading to the presumption that he will play the role of Cornell.

Additionally, film industry publication Backstage has posted casting notices for roles to appear in Black Days to play characters of “Young Chris,” a “Doctor,” “Hotel Maid,” “Road Manager,” and other parts. The casting call does note that production will have to abide by “COVID-19 guidelines” and that “filming is done in small groups only.”

Last year, it was reported that production for a forthcoming documentary on the late Grunge-era rocker is underway from Hollywood director Pete Berg and producer/actor Brad Pitt. Pitt was one of the many notable entertainers who were in attendance at the “I Am the Highway: A Tribute to Chris Cornell” concert event at The Forum in Los Angeles in January 2019.

UPDATE: Following reports of the forthcoming film project on Monday, the estate of Cornell–led by his widow and Soundgarden adversary Vicky Cornellreleased a statement saying the film project has not sanctioned or approved by the estate, nor has anyone from the project reached out to them for approval or authenticity assistance.
