Which mcu movies explore the multiverse?

The Marvel Cinematic Universe (MCU) has incorporated the idea of alternate realities and parallel universes in some of its storytelling, a concept often referred to as the multiverse. While the overarching cinematic narrative has touched on alternate timelines and divergent worlds, the precise movies that explicitly delve into multiverse mechanics are not identified in the available evidence. This means that, without further verification, it is unclear which films can be definitively classified as exploring the multiverse. Viewers interested in this theme should look for clues in plot elements that involve characters encountering alternate versions of themselves or other worlds, but confirmation would require additional sources. As such, any specific list remains tentative until corroborated by reliable references.
