During this isolation, I would be interested in suggestions of great movies you like.

Real good one @r_f_sayles. Wings Of Desire is, amongst other things, one of the most beautiful looking films ever made, breathtakingly so.

The Black & White cinematography in the Coen Brothers The Man Who Wasn't There (starring Billy Bob Thornton, Frances McDormand, James Gandolfini, and Scarlett Johansson) is the best I've ever seen: deep, deep black, and shimmering, almost iridescently-silver white. 

• Akira Kurasawa - RAN.
• Terrence Malick - Thin Red Line.

There can be only one:

The Exorcist

VERY powerful!!!! 

Western – Directed by Valeska Grisebach

A Separation – Asghar Farhadi

In the Fog – Sergei Loznitsa

Broken Circle Breakdown – Felix van Groeningen

The Kid With a Bike – (or any film by) the Dardenne Brothers

Couscous – Abdellatif Kechiche

Man on Wire – James Marsh

The Lives of Others – Florian Henckel von Donnersmarck

• Au Lait.I shall have to look out Shadows of Forgotten Ancestors as you obviously have a great knowledge of movies. Thanks.

• I wish to add The Lives of Others as a must-watch IMHO" In 1984 East Berlin, an agent of the secret police, conducting surveillance on a writer and his lover, finds himself becoming increasingly absorbed by their lives."

• tonykay -Great idea, really enjoy finding recommended movies I haven't watched. As with all of us here we most probably have seen most of the above mentioned but there's always the gems that slip through the cracks.

• dpac996- .Lilyhammer.Nice choice.The Miami Steve Van Zandt(or Little Stevie or just Steve Van Zandt, or E Street band legend) shines in what is a hilarious Tv Series set in Norway and available hopefully still on Net flix in collaboration with a Norwegian broadcaster. All 3 series are gems.

• Man Bites Dog.
  

• A black comedy (shot in B&W )and requiring English subs the story of a professional  Serial killer. I found it really funny.
• Ran.
  
• An epic Kurosawa. Ran is Japanese filmmaker Akira Kurosawa’s reinterpretation of William Shakespeare’s King Lear. Other films he made including Seven Samurai are well worth investigating.
• The Game.
•  An Australian Comedy from the late seventies. An Aussie sense of humour is not required, its funny to all.
• Fitzcarraldo.
  
• Werner Hertzog Dir "The movie is wonderful, but the story behind the making of the movie is practically unbelievable - but it is true. I urge anyone interested in Fitzcarraldo or the hazards of motion picture making in the jungle to also see Burden of Dreams, Les Blanks’ movie about the making of Fitzcarraldo"
• The Tin Drum. "
  
• The Tin Drum is a 1979 film adaptation of the novel of the same name by Günter Grass. It was directed and co-written by Volker Schlöndorff. It was mostly shot in West Germany. "
• Come and See.
• Another epic Movie. "After finding an old rifle, a young boy joins the Soviet resistance movement against ruthless German forces and experiences the horrors of World War II."
