I'm sure there are millions and they will differ for everyone, but we are rewatching loads of older films during lockdowns, so some great ones have reappeared for me.
For example: One for me recently was 28 Weeks Later.
Robert Carlisle character and his wife are in a farmhouse, having dinner with a jovial bunch by low candle light. Very atmospheric. Candles giving off a very shadowy, late evening vibe.
A few minutes later, the zombies are at the doors and windows, pulling off the wooden slats and boards to reveal broad daylight and the horror that the family have had to live in the dark avoid discovery.
It was a great scene that stuck with me.
What are yours?
