I Need To Know : Movie from the 1960s or 70s. A woman in a red/orange wasteland with fog.

I have never seen this movie but it was on a list of weird movies and I saw a YouTube video about it and some pictures.

Main character is a woman and the whole movie has a red/orange tin with red/orange fog everywhere. I seem to remember her standing next to a boat dock with a giant boat.

It has a very grimy industrial look to it with reg/orange fog everywhere.

I don't know anything else about it.

Some of your description sounds like Night of the Comet.

I saw it, it was about a group of people traveling after a nuclear war. Brit film, circa 69-71. Sorry, don't recall name.

Sounds very much like Red Desert (Il Deserto Rosso), Michelangelo Antonioni's film of 1964, and his first in color. Monica Vitti , the star of his three previous films, is the woman drifting through postwar industrial Italian city, and Richard Harris (dubbed, I would assume) is her co-star.

You beat me to it, but yes, this is the very same film I was thinking of. I saw it on TCM a while back.

Red Desert matches a lot of your description. Some of it also reminds me of Dead Man's Letters (1986)

It's a Russian post-apocalyptic film. It's largely shot with mainly orange tinted film. I remember this playing late night on British TV, probably late 80's or 90's. There's a brief scene with a big Hovercraft. It's on YouTube, as is Red Desert.
