Director of Photography Jack Cardiff in his book "Magic Hour"(1996), wrote about the immense planning for the ten minute takes in Under Capricorn and concluded:
"If a cameraman is supposed to 'paint with light', Hitchcock painted with a moving camera. On :his other films, using normal techniques, he was able to use his camera with such exciting :bravaura, cutting from one shot to another to obtain rhythmic emphasis.
And that's where Under Capricorn failed in the end. Despite Hitch's brilliant ideas on how to :keep the camera moving, he was fatally inhibited by the inevitable loss of tempo."
