Peter Suschitzky’s cinematography in TESB is one tough act to follow.
Alan Hume actually walked out because he didn’t like how GL was treating Marquand. Alec Mills took over for the last month of production.
Also, the film stock used for the movie is what resulted in a blue tint over everything.
The Arriflex thing is probably down to economy. They were shooting in England for large stretches of the movie so maybe it made more sense to rent European.
