In fact, it's the most popular movie franchise ever.
But what if you could use maths to help explain the popularity of the MCU?
That's just what Professor Matt Roughan is doing.
Matt is an ACEMS Chief Investigator at The University of Adelaide.
One of the things Matt explores is cast size and whether it makes a difference. Interestly enough, he uses some ideas from ecology to predict a movie's popularity.
How cool is that?!
