From IMDB:

A French adaptation of the second (and much less well-known) version of D.H. Lawrence’s erotic tale.

From Kanopy:

Kino is now proud to present Lady Chatterley in a new, two-part, Extended European Edition featuring nearly an hour of additional material excluded from the film’s theatrical cut that explores the emotional and sensual borderlands uniting sex, love, and loyalty with even more intelligence, passion, and power than before. Through extra footage never seen in the US, director Pascale Ferran’s “rapturous visual tone poem” (New York Times) becomes both a highly erotic immersion into Lady Chatterley and Parkin’s passion and an equally frank and unsentimentally provocative portrayal of a marriage hobbled by war and ultimately torn apart by hypocrisy.

From KANOPY you can stream 6 hours and 5 minutes of this French adaptation with English subtitles. Actually it is 3 versions of the same film where each runs for 2 hours.  Whatever difference there is between the first and the other two I could not find. Watching just the first 2 hours is more than sufficient.

When was the last time your watched a naked man and naked woman frolic in the rain? When was the last time you watched a naked man and woman in front of a blazing fireplace where he decorates every part of her body with wildflowers?  Clearly this version of “Lady Chatterley’s Lover” is the most explicit  and also the most photographically beautiful  version I  have ever seen
