2001: A Space Odyssey immediately comes to mind. But then I had to dig deep for others and some movies I loved but forgot about.
The Assassination of Jesse James by the Coward Robert Ford — amazing movie
Lawrence of Arabia another classic.
Raging Bull.
So many - but some here I haven’t heard of so this will help movie night.
P.S. Metropolis is one of my favourite movies.
And I seem to be recalling Brazil - 1985. Another absolute classic.
