How to find out about special cinema showings?

[413x]

I keep missing out on when cinemas screen old films again.
Usually someone posts they've seen it or they are going "tonight".
Was really annoyed to miss out on alien.

Is there some sort of resource for up and coming special screenings at your local cinema?

Anyone know for odeon? That's my local one.
Would be nice to get it passively. Ie a dedicated email vs looking at an app regularly
