Genre research/ Film opening analysis

So me and my group decided to view multiple film openings on our own time. I decided to rewatch three of my personal favorite film openings from some of my personal favorite films. One of the best film openings that I think everyone can agree with is the Dark Knights bank heist film opening. Another was the casual Resevoir Dogs diner opening. Finally, the third was 2001 a space odyssey brilliant DAWN OF MAN opening. First lets start with the Dark Knight, arguably the best superhero film ever made and the best adaptation of the comic book character. The film opening is the perfect blend of character introduction and world building. The opening shot is of what we later find out is the Joker standing at a streetlight with a clown mask at his hand, and as the opening progresses we realize that he's planned a very elaborate and well thought out heist that will leave no strings attached. Through the various shots in between heist members we get a brief overview of Gotham city and are shown how vast and constantly working it is. The interesting part that Christopher Nolan uses to build the Jokers character without even really seeing him, is how he told each of the heist members to kill a certain heist member for a bigger cut. This shows the Jokers sick and twisted genius as he is the last one alive in the end, and he is left with the entirety of the money and has left no possible trace back to him. The second film opening that I viewed multiple times was the opening to Resevoir dogs, I believe its Quentin Tarantino's first film but I could be wrong. The entirety of the opening takes place in one location, a diner and specifically one diner table where there are a couple of men just casually talking. The amazing thing about this opening is the pure simplicity and Tarantino's perfect use of dialogue. You're quickly given a rundown on the majority of the characters. First were pretty much shown the leading figure of the group which is Mr. White, quickly with simple dialogue were shown that he's experienced in this type of work and is shown to be mature. Mr Blonde on the other hand is shown to be more of a smartass and might just end up bringing more conflict later in the film. The entire premise of this opening is based on the simple idea that Mr. Pink won't tip the waitress that's attending them, then a conflict arises because the other group members are calling Mr. Pink a cheapskate. The final opening I viewed multiple times was the now Iconic DAWN OF MA N introduction to 2001:a space odyssey. The opening basically depicts what human nature is and what it evolved from. Its meant to show us the natural curiosity we have as mammals and to shows other darker emotions we may feel as predators ourselves. Stanley Kubrick is arguably one of if not the best filmmaker of all time and this introduction is the perfect opening scene to one of his best films. The best shot in my opinion is the sequence when we are shown the primate showing us his curiosity with the bone remains of a creature, and seconds later how his mind shifts to destruction as he begins to bash the bone against the rest of the other bones. This in my opinion was meant to shown our natural reaction to things and how we have been hard wired to think this way since the DAWN OF MAN.
