This sure was a compelling film

Why do some expensive 60s movies like this have unrealistic colour and lacks sharpness where some Brit movies of late 60s look 'real' as if its now ?

@kenfig Some of that is simply due to a film not being well preserved. This trailer for example has not been preserved well (most trailers aren't) and has begun to deteriorate, hence the orange-ness. The actual film has been better preserved & looks more realistic. While, Bond films of the '60's look the same as when they came out since they are constantly being restored. (Also, keep in mind that some Hollywood movies were made with brighter or stylized colors as a conscious choice)
