With Black Widow on the way, it's time to go back and rewatch every Marvel Cinematic Universe movie leading up to this point - but where can fans watch them all online? The MCU got off to somewhat of a humble start in 2008, first with the release of Jon Favreau's Iron Man and then quickly following that up with Louis Leterrier's The Incredible Hulk. Of course, it wasn't until 2010 that the franchise started to take shape, with the full introduction of S.H.I.E.L.D. in Iron Man 2.

Even then, things were still quite small, at least compared to how the MCU looks today. Joss Whedon's The Avengers catapulted the franchise to new heights in 2012, and Marvel Studios has been soaring ever since. After Thanos appeared in the movie's post-credits scene, the supervillain became the endpoint for the shared universe's first "saga," which officially wrapped up with Avengers: Endgame in 2019. And getting to that point meant almost two dozen movies had to release. So far, Phase 1, Phase 2, and Phase 3 of the MCU consist of 23 movies in total.

While many fans have purchased all 23 movies on DVD or Blu-ray (possibly through each Phase's official box set), for fans who don't have all the movies and want to quickly watch them online, we've put together a simple and easy guide to find them.
