Marvel's latest Disney Plus series, "Ironheart," is almost here, and these are the MCU movies you need to stream now to prepare yourself.

Riri Williams was first introduced in Black Panther: Wakanda Forever, so it makes sense to watch this Marvel Phase 4 movie before you dive into Ironheart. But, if you're going to watch the sequel, you might as well watch the first film, too. It's one of the best Marvel movies, after all.
