Gun barrel sequence

A gun barrel sequence is when the beginning of a movie or TV show shows a close-up of a gun barrel, zooming in towards the barrel opening. This is usually accompanied by suspenseful music and is meant to get the audience excited for the action that is about to happen in the movie or TV show.

Think of it like a sneak peek at what's coming next, but it's done in a really cool way with a close-up of a gun barrel. It's kind of like when you bite into your favorite candy and you know it's going to taste awesome because you can already smell it and feel it in your mouth. The gun barrel sequence is like a preview that gets us pumped up for the action that's about to happen in the movie or TV show.
