Jack Black is a busy man but it looks like he's been secretly busier than we imagined as he's announced that a sequel to the 2006 cult musical comedy 'The Pick of Destiny' is on the way.

Black and fellow Tenacious D member Kyle Gass were performing at Shaky Knees Music Festival in Atlanta yesterday when Black made the surprise announcement that a sequel movie will be released in October.

"I don’t know where you’ll be able to see it, but we have decided that it’s happening and it’s coming out," Black told the crowd.

No further information was given but seeing as there are many various avenues for a film to be released these days (hi, Netflix), we imagine it'll be streaming into our homes.

Black previously teased that Tenacious D were working on a rock-opera album titled 'Post-Apocalypto', telling Conan O’Brien: "It’s a post-apocalyptic musical comedy, and the idea is that you know, you’ve got Pink Floyd The Wall, and you’ve got Tommy [by] The Who, and those are the only true rock operas in existence."

"You hear rock opera all the time. There’s only two rock operas. Ours is gonna go right there, somewhere in there, and all of the other ‘supposed rock operas’ can suck it! ‘Cause they suck."

'The Pick of Destiny' served as both the band's second album and the film's soundtrack so if we were betting people, we'd put some money on this being the same.
