At the very beginning of "About Elly", during the titles, we seem to be seeing some sort of papers being shoved through some sort of slot – from the inside of whatever they're being shoved into. What are we seeing? Are those letters being inserted into a letter slot in a door? Or ballots being put in a ballot box? Or something else? And what significance does it have to the rest of the movie?
Farhadi explained it was an alms box that travelers put money in before a trip to ask for a safe trip, and yes, there was some dialog about Elly putting money in an alms box, but I never connected it to the opening scene.
As an Iranian person, I should answer this. In Iran, we have some boxes in streets and roads that called 'Sandogh-e Sadaghe'. They Supported from government organizations. we put money on it to help poor peoples. there is an old belief that if you help to poor before a travel, you will be safe while you on it.
