Only 40 minutes long!?

There are supposed to be two versions: http://www.ew.com/article/2016/05/02/terrence-malick-voyage-time

...Malick isn’t known as a documentary filmmaker (his movies more often traffic in fantastic imagery and dreamlike whispers), but Voyage of Time has two separate versions. The documentary will reportedly be narrated by The Tree of Life star Brad Pitt and last 40 minutes. There will also be a feature-length cut narrated by Malick’s Knight of Cups star Cate Blanchett, but release date on that is still unknown...

if i remember correctly there were talks about two imax documentaries out of this. i might be wrong though. anyhow i expect imax version to be a straight forward documentary compared to theatrical cut.

edit: seems like i was correct

According to a complaint filed in New York federal court on Friday, Malick was supposed to direct two 45-minute Imax films and a 90-150 minute feature film version of Voyage of Time.
