What ‘style’ is a film like ‘The Man from Earth’ and what are more films like it?

I simply noticed 'Mass' and the type of the film jogged my memory of 'The Man from Earth'.

It virtually feels like a stage play on film, and in some instances, I feel they are diversifications of stage performs to film. Its films the place the actors performances and the writing are doing 99% of the heavy lifting. The budgets are sometimes fairly tiny, the film is virtually set in a single room with a group of characters that are strongly outlined and have various views on a situation or differing backgrounds and they discuss by way of a downside or circumstance, every giving their very own distinctive and very well thought out views that make the characters really feel very actual.

What is the style for a film like this? I need to discover more however I don't know tips on how to seek for it.

Here's a checklist of films that come to my thoughts:

• 12 Angry Men

• The Man from Earth

• Mass

• Carnage

I'm certain there's more I've seen however these are those that come to thoughts and rattling, do I need more of it. I discover them so charming.

EDIT: Adding these from solutions for anybody that wishes a checklist:

• Sleuth

• The Guilty
