No, it’s not the theatrical version, the extended cut, the director’s cut, or even the final cut. It’s not even a fictional narrative. What is it? It’s a promotional film shown at conventions before the movie was released. You can read more about it at Giant Freakin Robot, which describes the featurette as “a fascinating relic with an awful soundtrack.”
Around the two minute mark they show the shooting of a scene that I don’t think made it into any public cut of the film. It appears to be a classic interrogation scene, the kind of thing you’ve seen in countless detective movies since The Maltese Falcon and The Big Sleep. I’m wondering if the noir elements were originally intended to be a lot more prominent than they ended up being.
