Learn Farsi: هنرورها اکنون در لوکیشن هستند.

The base word honarvar combines honar (art) with the suffix -var (possessing or characterized by). While it traditionally meant a skilled craftsman or artist, in modern Farsi media jargon, honarvar specifically refers to a background actor or "extra" on a film set. The -hâ simply makes it plural.

Why does the sentence use aknun for "now" instead of the more common alân or hâlâ?

aknun is a more formal or literary equivalent of "now". While you would use alân in everyday conversation, aknun is frequently used in news broadcasts, formal announcements, or professional production updates to sound a bit more polished and official.

Is lokishen just the English word "location"? Do Iranians really use it this way?

Yes, it is a direct English loanword! However, it isn't used for general everyday places (like asking for the location of a restaurant). It is specifically adopted as industry jargon for a film, TV, or photography location outside of a studio, exactly as it is used in English media production.

The English translation says "on location", but the Farsi uses dar (in). Why not use a word for "on"?
