What are some movies where everyone is incredibly competent at something?

Just finished watching September 5 and what made the movie so compelling to me was how damn good everybody was at their jobs.

From Marianne finding out the names of the athletes to the woman making the captions and everyone in-between. They did their job or task with the the utmost professionalism and skill. And on top of that, everyone worked together so well.

What are some other movies with similar levels of competency?
