Avengers: Infinity War is now available on Digital HD, a home release which includes four deleted scenes among its bonus content. There’s really one truly never-before-seen scene, however, with the other three being extended versions of scenes that ended up in the theatrical release.
Let’s go through what happens in each of those four scenes. Spoilers ahead, obviously …
Running one-minute and twenty-three seconds, this early scene includes a cameo by Iron Man director Jon Favreau, reprising his role as Tony Stark’s harried security chief-flunky-pal Happy Hogan. The scene retains the larger exchange between Tony and his fiancee Pepper Potts in the park talking about Tony’s dream where they had a child named Morgan. The theatrical version of the scene ends with a portal opening and the arrival of Doctor Strange and then Bruce Banner.
