How region affects results

The region parameter acts as a presentation filter, not a data filter. According to the TMDB region support docs, it affects:

• Release dates — Returns the region-specific theatrical release date when available, falling back to the primary release date if not found
• Age certifications — Returns the content rating for the specified country
• Watch providers — Filters streaming/rental availability to the given country
• Filtered lists — Endpoints like "now playing" and "upcoming" use the region to determine what is currently in cinemas in that country
