Wim Wenders' "Pina" is a 3-D documentary that explores the legacy of the late modern-dance pioneer and Werner Herzog has directed "Cave of Forgotten Dreams," an exploration of ancient paintings in the Chauvet caves of Southern France.
Wim Wenders' writing were an early inspiration to me when I was young and just becoming interested in filmmaking, and Herzog was as an artistic father to Kidlat Tahimik- my ultimate inspiration in filmmaking! So interesting that these filmmakers choose to embrace 3D, and for documentary no less! I'm not even a little bit sure of how I feel about it.
