It’s not really something I bother noting, as most films do to some degree (although they can throw a curveball with a four act structure), so the cheap answer would be: horror anthologies.

A bit difficult to answer since three-act structure is one of the most used model in long stories and especially in movies. The Setup, the confrontation, and the resolution are pretty much the standard. Maybe some found footage horror like: Blair Witch Project, Rec and so on.
