I think Pigment has done most of the work.
The picture I am building so far looks something like this:
Pigment:
* came up with the idea for the Hindenburg move
* provided the Hindenburg ship itself (from the Main Grid)
* played a large part in direction
* helped out with the filming
* provided expertise/advice
* edited each version of the film
Achilles:
* played a large role in recruiting actors
* helped with a lot of the arrangement (e.g. organising what scenes would be shot next based on the actors/backgrounds available)
* did most of the filming
* helped out with the directing
* played a part in drafting the videos on creation as a test audience
