OP was simply referring to nominees as best picture in the Oscars between 55-65 to make his point.

With cherry picking you can make any point you want. It not only ignores most of the films in that era, it even ignores most of the best picture Oscar nominees, to say nothing of the fact that OP so wildly mischaracterizes 12 Angry Men and Sweet Smell of Success that I wonder if they've seen the films in the first place.

I have to agree with OP, 12 angry men is a fantastic movie on many levels, but it really feels more like good Shakespeare than 12 real dudes discussing execution and their consience

The noir films was a significant inspiration for the nouvelle vague. They were highly regarded by french critics, which even gave the genre its name.
