Maybe Tenacious D did do us all some good, after all

The poor-but-predictable showing of The Pick Of Destiny has presuaded Jack Black that he's better off doing other people's stuff:

"It was a body blow, mainly because we had so much fun making it. I got a lot out of the writing. I was psyched to write more screenplays, but that kind of killed my writing career."

Perhaps he should have tried writing a comedy instead.
