One is not enough, and a lot of great movies where already named, still, some great movies are missing:
- Heat (Michael Mann) Every single time I see it, it is brilliant and I discover something new
- Jin Roh (The original animation movie), awesome atmosphere and only after the 2nd viewing one can really appreciate it
- Near Dark (1987) Why the hell did nobody ever produce something like this ever again?
- Miami Vice (Michael Mann), 'Style over substance', in a great way, although I have the shaky camera
- Seven Samurai
- Casablanca
- Strange Days
- Point Break
- XXX (Nobody understood that it was a parody back in the days :-P)
- What we do in the shadows
- Brazil
- Rocky
- Eternal Sunshine ...
- The city of lost children
- Leon the professional
- Dolls
- The Killer (The original of course)
- The last unicorn
- Dark City
- The thing
- The Lost Boys
- Spirited Away
- Donnie Darko
- Rashomon
- Brother (2000)
- Parasite
- Hatsukoi (First Love)
... from the top of my mind. :-P
Great pick!
So many quotes from Casablanca are part of our everyday culture... and AFAIK it is the first movie ever to feature a flashback in a flashback. Combined with the awesome cast of actors this is a masterpiece. :-)
