Has the film already started?
GIA — the 'gi' sounds like the 'j' in 'jam'. One clear syllable.
Ask when you arrive and are not sure whether you are late. Useful at the entrance or with an usher. Also appropriate when re-entering after a toilet break.
Italian cinemas typically have 15–20 minutes of commercials and trailers before the main feature. So even if you are technically 'late' by the advertised time, you may still catch the start of the film. The actual film start is called 'inizio del film' as distinct from 'inizio spettacolo'.
Siamo in ritardo?
Are we late?
Simple question about lateness — can be directed at a companion or staff.
Il film è già iniziato da quanto?
How long ago did the film start?
Asks how many minutes in it is.
Si può ancora entrare?
Can we still go in?
Checks whether late entry is permitted.
Italian cinema advertising before films ('pubblicità') is extensive — often 15–20 minutes. Regulars account for this and arrive slightly late intentionally, a habit sometimes called 'arrivare all'italiana'.
