Left hand or left cheek

Tafas (offering a dish)- Bedu food. Lawrence (reluctantly, taking a bite with his left hand)- Good. Tafas- More? Lawrence (even more reluctantly takes a second bite)

-screenplay by Robert Bolt

Almost all movement goes from left to right. David Lean said he did this in order to emphasize the film as a journey…The master interpositive produced by Technicolor in 1966 had Reel 2A flipped so left and right were reversed on screen for about ten minutes…it was nearly impossible to spot this error.

If David Lean had wanted to film a journey, he could have followed KhairAllah on the Darb up from Nahud. He’d have seen no left hands eating reluctantly from the asīda bowl, only us keeping the north wind on our left cheek, heading NNE to Cairo, the same direction as Aqaba to Damascus but three times the distance.
