Best films about loneliness?

Does anyone know this movie? No title, and the user is banned.

Last Life in the Universe. :P

Ruang rak noi nid mahasan [Last Life In The Universe]

I don't think The Remains of the Day has been mentioned yet.

There's a new one from Hungary I watched a couple days ago... On Body and Soul.

Anna Karenina (the 2012 film plays up Karenin's loneliness and Anna becomes lonely when she is cast out of society).
Shame
The Woodlanders

Aussie film 'Somersault'.

Edward Scissorhands
Der Himmel über Berlin
The Lobster
The Martian
The shape of water

"Room For Rent" (2019)

Someone mentioned Midnight Cowboy, and I agree.

It is not the major theme, but lonely isolation is an under current in Green Book.

I think it is also an underlying theme in The Pawnbroker.

Two of the most heartbreakingly lonely films I can think of are:

The Sterile Cuckoo

La Strada

Did anyone mention Kelly Reichard's Old Joy ? Gus van Sand's Gerry ?
