I have not. I have, however, done three series for Youtube and one for WB.com. All told, several million dollars worth of web videos.

None of them were over seven minutes.

It's also worth noting that their highest rated video, for ep II, is in nine parts.

Part 1 has 2.6m views.

Part 2 has 1.3 - click through to part II is 50%.

Parts 3 through 9 have around a million views each. So it's pretty safe to say that the appetite for a 40-minute review is half the appetite of a 9 minute review, all else being equal.

A 60-minute TV program, minus commercials, comes in at around 42 minutes these days. So as far as commitment, we're in the same range as, say, LOST or Breaking Bad. Can you fill up that much time? Sure. Should you?

No.

I saw PROMETHEUS with an IATSE camera operator, a Cinematographer's Guild cinematographer and an Illustrator's Guild storyboardist/designer. Between them they were instrumental in creating Star Trek, After Earth, Zodiac and the Chronicles of Riddick.

We couldn't have found 40 minutes to say about Prometheus and of the four people there, three of them had worked with Ridley Scott and/or Damon Lindelof and/or Charlize Theron in a professional capacity.
