Yeah, sure, Jack White is a busy, busy dude. He's got three bands, give or take, and he's got his own record label now, for which he's producing (and playing drums on) four or five records.
But wait, there's more: In an interview with The Dead Weather on Self-Titled, White also indicates that The White Stripes are making a movie:
Then also, Third Man Films. The White Stripes are releasing a film this year, and when I go back home in a few days, I'm going to mix all the music for that, which is like 40 songs, so that's going to take a lot of time.
I can only assume that this is not an authorized version of the bootleg Nobody Knows How to Talk to Children, though you know what happens when we assume. Read more here.
