Update (9/22): The first official trailer for the Green Day American Idiot documentary, Heart Like A Hand Grenade, has arrived. Get an exclusive look into the making of the record by pressing play above.

Original Story (9/15): Pop-punk prodigies Green Day are hitting the silver screen. The group's now-iconic concept album American Idiot will get the documentary treatment next month. It's called Heart Like a Hand Grenade and it hits theaters October 15.

The film follows the band's writing and recording process and was somehow lost along the way...until now.

Director John Roecker released the following statement:

“I told [Billie Joe Armstrong] he should document the recording of the album and he said they had tried and it never worked. I suggested that he set up tripods around the studio and just have cameras run so it would not be too invasive of the process of the recording (I was hoping he would get my hint!). Then I got a phone call on a Friday night and he said he and the band will be in Los Angeles on Monday and why don’t I be the tripod. Thus began my nine months with Green Day.”
