Why we stock silent films

In a silent film, nobody can explain how they feel. The camera has to show you.

What the silence does

Without dialogue you start watching differently: hands, doors, who is standing at the edge of the frame. It is the same attention a good novel asks for.

Everything is subtext when nobody can say it out loud.

Start with Metropolis

Metropolis (1927) is a good first silent film because it is so big: a whole city, built in layers, with the workers kept underneath. You don't need any background to follow it.

Then try the talkies that still listen

Some later films kept that habit of showing rather than telling. Brief Encounter is almost entirely about what two people can't say, and Tokyo Story barely raises its voice.
