This is the best scene in cinematic history

1917.

the whole movie is one continuous scene, albeit broken briefly by a period of unconsciousness, never done before or since.

Other films have used this technique.

Right, lots of films are a single scene. A decent amount of those are single takes. Russian Ark is probably the best single take full length movie (IMO)

1917 isn't a single take though, just used special effects and other filming techniques to appear as a single take (I'd argue that its not a single scene either). Birdman won the academy award for best picture while doing the same thing just a few years prior to 1917. There are probably a hundred movies that have done something similar, many every year!

What's the best movie that is a single scene (whether 1 take or not?)? 12 Angry Men?

Rope is another that was/wasn't. Maybe not as good as 12 Angry Men but 12 Angry Men being a play centering on dialogue was probably easier to pull off.

Like I just said you do not have to live in NYC or Boston. Find a smaller city!

LOL, that is one great scene in one crazy clusterf*ck of a Tarantino movie ... Clooney, Keitel, Juliette Lewis, Danny Trejo and, of course, Salma Hayek! Hard to believe it's 28yo now.

Love the music, too.

Rope is ten long takes. They could only shoot for ten minutes at a time because limitations with the film capacity of the cameras they used.

Very difficult to pick just one as everyone will have a different opinion but for me this would be a contender, just because I like the film so much:

And yes I know the science is very shaky but take that out of it.
