Seven Questions

Does the lighting scheme feel ‘naturalistic’ or not? Is this the case for both interiors and exteriors?

I feel that the lighting could be hyper real, an eggagerated verision of natural. the highlights are harsh and bright, while the flouresent lighting is used for dramatice effect in the interiors, whilst in the exteriors the bright highlights allow for a noirish closed view or the world.

What variety of movement is utilised in the chase sequences – tracks, hand‐held, Steadicam? How is this
range used in the cutting? Which focal lengths seem to be most commonly used?

I don't think the film used hand cam, but more track movements, to give a differnt feel to the film. like were watching them. some scenes especially diolque seems to have used a wide angle lens, maybe a 20mm but the action scenes, Especially the last sequence used a long lens, which gives a different perspective.

“The film's world is shadowy, decaying and intentionally dated. At the same time Somerset and Mills' slow
voyage from claustrophobic murk into blinding light makes for a vivid dramatic metaphor”. Do you agree?

Yes, the lighting help set the worl were in and the location as well as atmosphere, the change provide a great contrast for the film and it's ending.
