I’m way busy and way behind, so this week’s Friday movie news dump will have to itself be dumped. Nevertheless, I’ve got time for trailers. Also, yes, when you start mentioning grosses in connection with a Werner Herzog documentary about miraculously well-preserved cave paintings, you’ve definitely been writing too much about movie box office.

In any case, here’s a trailer for “Cave of Forgotten Dreams,” the latest documentary from Herzog which really will be in 3D. Take a look.
