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

After giving it some more thought, and staying away from the horror themed, you might wanna check out:
Lonely Are The Brave
Paths of Glory
Jean de Florette & Manon of the Spring
(kind of a part one and two)
Hombre
Lawrence of Arabia
Dr. Strangelove
Charlie Varrick
The Taking of Pehlam, One, Two, Three (the original)
Kiss Kiss, Bang Bang
Snatch
American Hustle
Killing Them Softly
In Bruges
Rocknrolla
Road to Perdition
Arsenic & Old Lace
Public Enemies
Fargo
Raising Arizona
No Country For Old Men
Winchester ’73,
The Far Country
Rear Window
The Searchers
She Wore a Yellow Ribbon
Donovan’s Reef
Liberty Valance
The Magnificent Seven (the original)
The Naked Spur

That should keep you occupied for awhile

All the best,
Nonoise
