Closed room mystery/Being stuck somewhere

I love closed room mysteries, escape rooms, killing games, any kinds of stories where a group of people are stuck in a room, or an island, a town etc, and must figure out what's going on/how to escape.

I'm up for human stories, horror, thriller, mystery, disasters, hostages... heck, it may even be a romantic comedy and I'll watch it. Any country is fine.

Any recommendations, please?

That is, if I haven't already seen them all, here are at least some I've watched:

Thank you for the replies. I'm watching a few of the suggestions already, and made a list for these types of series/movies. I hope there will be more recommendations. :)
