I once heard an anecdote about the great cinematographer, Sven Nykvist.

It was in-between setups on the set of Bergman’s Through a Glass, Darkly and Nykvist was relaxing under a tree with a fellow crew member. A production assistant came over to tell Nykvist that he was needed on set immediately.

The crew member with whom he was sharing a moment of relaxation, turned to him and said: “Sven, let’s hurry, they need you.” Nykvist turned back and replied “No rush, without us, it’s radio”.
