What Vitaliy said, check Shian's well thought out CGHear tool set.

Mimicking the entire look/grade of a film is... a bit silly, technically and experience wise, just happens to be so much fun the journey (personally I find colour to be as important in video/fim's language {re/de}construction as every other step of the process) to understand, balance and reveal the colour identity of your images so one can then "fucked" them all up :P

BUT we all need models and contexts; so as an interesting analysis tool, Tone Hacker by good Guillermo Luijk (free), also 3dLUT creator by Oleg Sharonov (70$) have both a curve hacking thingie/module. What that means is that you can extract the curves of a given image and anal-yse its specific look. Furthermore you can load this curve (.acv) into photoshop and apply to whatever image you feel like and even export it as a LUT.

Though it is obvious, the image/film one is extracting the tone curve response from has a context and most of the times just copycating (verbalised) and applying that look into other image would result in... a "ghost story". I honestly think it is far more interesting telling your own story with your own words, maybe baby words in the beginning, this for instance is the stage where I am currently at, but then (dreams, dreams) simple true poems of resounding beauty.

That should not take anyone of playing around with whatever is available and make dada compositions =)

PS
Have in mind this is as Q&D proof of concept as it gets. I got a small screen grab and I didn't even convert it... knowing I would apply the curves over an image with totally different context, also values from the original video source footage (with or without CC). Proper accuracy was not really the main goal/concern ,-)

not to over simplify, but it looks like someone shot all overcast (gray) just took my lavender burst filter and slapped it on the whole thing, and added a little contrast curve.

edit: Oops I was just looking at stills. Just watched the video... most of what I said before holds true, but there's some monkeying with the shadow curves similar to a film stock transfer in CG Pro, Film Convert, or Resolve 11 similar to this:
