I don't know why you guys keep going on and on about film being made in Harrow. Just because KPP owns the operation does not necessarily mean anyone would think it were a good idea to move everything there. There is zero reason to do that and zero reason (aside from corporate legality games) to not just continue with what they're doing by contracting everything from the Kodak that is making the film now. Moving it all to the UK would be a stupid move of the highest order.
Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
