Here's the breakdown:
* Scripted Scenes: Most of the film, especially those involving Bruno's outrageous antics, were scripted and staged. This includes scenes like the "gay rodeo," the "Nazi fashion" segment, and the "gay wedding" sequence.
* Real Reactions: While the situations were staged, the reactions of the people Bruno interacts with are often genuine. They might have been told what was generally going to happen, but they were often genuinely surprised and shocked by Bruno's behavior.
* Docu-style Editing: The editing style and the way the film presents itself further enhances the "real" feel.
So, while some scenes were definitely staged, the film's strength comes from its use of real reactions and the blur between fiction and reality.
It's important to note that the line between what is truly real and what is staged can be difficult to discern in a mockumentary. The film's success lies in its ability to make you question what you're seeing and to get a reaction from viewers.
