What do you mean?
Do you mean when filming by standers reacted?
Yeah. Unscripted reactions of bystanders were included in the film. There are various articles kvetching about the fact that regular Germans reacted this way.
This says 300 hours of reactions were filmed. According to the director, the ones included in the film were "very representative". I don't know if that's true, but maybe so. https://www.theguardian.com/film/2015/oct/06/hitler-look-whos-back-director-david-wnendt-interview
