This Is Spinal Tap Production Studio

Spinal Tap Productions

The production company was called Spinal Tap Productions. They, uh, didn't do much diversifying.

Seriously. This company was one and done. It was formed and filed for the sole purpose of producing a single film, and was later dissolved. No Spinal Tap spinoffs, no Spinal Tap Saturday morning cartoons, no Spinal Tap breakfast cereal.

So yeah, they're donezo. Here in the States, at least. We hear they're still pretty big in Japan.
