According to The Hollywood Reporter, Bruce Sinofsky, who co-produced the METALLICA documentary "Some Kind Of Monster", has died after a battle with diabetes. He was 58 years old.

Sinofsky and Joe Berlinger — who founded production company Creative Thinking International in 1991 — also filmed the 1994 movie "Paradise Lost" on the West Memphis Three, a documentary about three teenagers convicted of murder.

Said METALLICA in a statement: "We lost a valued member of our family today as award-winning filmmaker Bruce Sinofsky passed away this morning.

"Bruce, along with Joe Berlinger, was the architect of our film 'Some Kind Of Monster'. Smart, funny and dedicated, Bruce was with us almost every day in the early 2000s and was an integral part of helping us to navigate the rough waters during those times. Although not very welcomed at times, he was there through some of the darkest times of METALLICA. He became a dedicated comfort and visual lifeboat, while objectively observing the unraveling and rebuilding of our inner and outer selves.

"We admired Bruce and Joe's work in 'Brother's Keeper', but, of course, were blown away by what Bruce and Joe accomplished with the 'Paradise Lost' trilogy of films. With their relentless work and attention to detail, Bruce and Joe's films drew attention to the miscarriages of justice associated with the trial of three teens accused of murder and helped to lead to their eventual release from prison after over 18 years behind bars.

"After 'Some Kind Of Monster', Bruce went on to do more brilliant work on the Sundance channel series 'Iconoclasts', and History's '10 Days That Unexpectedly Changed America', along with numerous other film and television projects.

"Our thoughts and prayers are with Bruce's family and friends.

"We will miss Bruce. A courageous man with deep empathy and wisdom who wasn't afraid to dig deep to tell the story.

"RIP Bruce."

METALLICA released a 10th anniversary two-disc Blu-ray edition of "Metallica: Some Kind Of Monster" on November 24, 2014. The new edition of the film was made available digitally and via VOD for the first time. It also contains a new bonus feature, "Metallica: This Monster Lives", a 25-minute follow-up segment filmed at the 2013 Toronto International Film Festival during the premiere of the band's second film, "Metallica Through The Never".

The segment features interview footage with the band and "Some Kind Of Monster" co-directors Joe Berlinger and Bruce Sinofsky in which they all look back at the decade since the release of the film.

Originally released on July 9, 2004, "Metallica: Some Kind Of Monster" followed the band through the three most turbulent years of their long career, during which they battled through addiction, lineup changes, fan backlash, personal turmoil and the near-disintegration of the group during the making of their "St. Anger" album.

"The presence of the cameras helped keep the process on track," METALLICA drummer Lars Ulrich told TheWrap. "There was another set of eyes and ears there. Sometimes when somebody else is in the room, you watch your p's and q's a little more. I think it kept the whole thing from derailing in some peculiar way."

While initially helping METALLICA towards restoring band harmony, the film shows "performance coach" Phil Towle, a former psychotherapist who was brought into the picture in January 2001 to help James Hetfield, Kirk Hammett and Lars Ulrich repair their relationship with Jason Newsted, attempting to increasingly insert himself into the band's creative process, submitting lyrics for the album and even attempting to join them on the road.

"We were at a crossroads," Ulrich explained. "We had been really good at being able to compartmentalize a lot of this stuff. Suppress it with drinking or other extravagances. This was the first time we had to talk to each other, get to know each other and work stuff out … The cameras were there catching all of it."

"Some Kind Of Monster" also documented METALLICA frontman James Hetfield's spiral into alcoholism and decision to check himself into a rehab facility. Hetfield's re-emergence from rehab is when the film really gets into gear, with the chief worry in his mind whether or not he could do METALLICA sober.

"Hetfield went away, but we said, 'Why don't we keep filming? Because we think it's interesting,'" Ulrich told TheWrap. "We said, 'We trust you guys.' And they ended up being another set of eyes and ears in those rooms for the next 18 months as we dealt with the aftermath of Hetfield going away and all of the subsequent domino issues that came in the wake of that."

According to Ulrich, METALLICA had no idea how fans would respond to seeing footage of the band's touchy-feeling therapy sessions that ultimately healed the group and kept METALLICA from splitting up.

"As much as you want to control how people react, there are always things that throw you for a loop," Ulrich explained. "The fact that the music world was a little bewildered by it and the fact that the movie world sort of embraced the film was not something we would've predicted."

METALLICA is reportedly getting back to work on its tenth studio album.
