Glengarry Glenross is interesting, but foul language aplenty indeed !

Samsara is about visual imagery than being informative. I think they uses 70mm film for the making of both Samsara and Baraka. 70mm film is the bigger version of 'analogue' film tech used for big screen and planetarium. So I guess unless the future film makers are nostalgic about being analogue, otherwise it may be taken over by the latest 4K (Ultra HD) digital format.

I haven't seen Samsara in its totality yet. But Baraka really focuses on cycle of life, the irony of developed and under-developed lifestyle. Spirituality played an important aspect too.

Film like this can create stunning imagery of historical importance. Baraka has a small segment of World Trade Center interior scenes, which I think has become a monument as such.

Just to inform for interest sake that, the dreamer's actress is the same that acted in Casino Royale - amazing personality while in 007.

Thats right.
