Also ich hätte es jetzt instinktiv genommen.

This important sequence is to be found in chapter 2 of the film.
A fairly important scene can be found in chapter 2 of the film.

Seit wann haben Filme denn Kapitel?

Seit es sie auf DVDs gibt.

@dude - Ich hatte erst section geschrieben, dann fiel mir ein, dass Filmbearbeitungssoftware diese auch immer in Chapter aufteilt.

Vorsicht:
a scene "takes place" in ...
wird mehr dazu benutzt zu beschreiben, wo eine Szene spielt (Wohnzimmer, Wald etc.)

AFAIK, a movie on DVD is divided into scenes, not chapters.

A DVD is divided into chapters. A play is devided into scenes.

[edit] Chapters
DVD Video may contain chapters for easy navigation (and continuation of a partially watched film). If space permits, it is also possible to include several versions (called "angles") of certain scenes, though today this feature is mostly used—if at all—not to show different angles of the action, but as part of internationalization to, for example, show different language versions of images containing written text, if subtitles will not do (e.g., the Queen's spell book in Snow White, and the scrolling text in the openings of the Star Wars films). Multiple angles have found a niche in markets such as yoga and erotica.

Yes, and a film script / story is devided into acts...

Play = acts and scenes.
