I'm not sure specifically what 'nova roma novel' is about as there could be many novels with this name or a similar title. It could potentially be about a fictional version of a new Rome in some alternate history or a story set in a place named Nova Roma.
Without having read the 'nova roma novel', it's impossible to accurately name the main characters. However, it's likely that there could be a strong leader type character who is in charge of Nova Roma or vying for power. There might also be a character who is an outsider but becomes integral to the story, perhaps a traveler who brings new ideas to the city. There could also be a love interest for one of the main characters, which could add a layer of drama to the plot.
Roma can be considered a true story as it reflects real aspects of the director's upbringing. However, like many films based on personal experiences, it might have been embellished or reimagined in parts to make for a more engaging narrative.
The Roma back story is complex. Generally, the Roma people have a long history of migration. They are believed to have originated from the Indian subcontinent and gradually migrated westward over centuries. Their culture is rich in music, dance, and storytelling traditions. They often faced discrimination and marginalization in many European countries throughout history.
Partly. The movie takes elements from real life but also incorporates fictional elements for dramatic effect. So, it's a blend of truth and creativity.
Roma tells a tale that's both personal and reflective of a larger societal picture. It focuses on the everyday lives and hardships of its characters, set against the backdrop of a changing Mexico.
