To Me the first one in particular seems like a real "nothing" shot - it does not add anything to the audiences knowledge of Geidi Prime.
Now recently I happened to have reason to look up the old Gregory Peck version of Moby Dick, and then someone sent Me a link on Facebook to a thing against Japanese whaling and I recalled that in the novel of Dune, the Harkonnens had returned to power through the adroit manipulation of the "whale fur" markets.
In the novel, the whale fur business is concentrated on the Harkonnen colony planet of Lankiveil.
However, since Lankiveil is NOT in the movie version, I had the idea to expand the Harkonnen city environment with a shot that passes through the gruesome whale fur factory and ends with the existing shot of the hose washing the meat off the floor.
If it doesn't end up working here, I may use it in the 2nd filmbook sequence I am developing.
