A couple of days ago, details on the mid and post-credits sequences from Captain America: The Winter Soldier were revealed. One of them will carry the movie into Avengers: Age of Ultron. Kevin Feige revealed at the Captain America: The Winter Soldier press junket that Joss Whedon directed that sequence. If you want to read what exactly the scene entails click here, and you can watch the video interview with Feige below thanks to Collider. Below the video is another interview in which Scarlett Johansson gushes over the script for Age of Ultron.
This is what Johansson had to say when asked about Whedon's Age of Ultron script:
“I was just amazed—Joss [Whedon] is something else, he really is. He locks himself away for God knows how long; I think he has the dark circles to prove it. [He] just came out with something totally solid. I was really impressed by his ability to make this ever-expanding Marvel universe feel very close-knit and cerebral and progressive. I mean this movie feels like the continuation of The Avengers, it doesn’t feel like a tag-on or the rehashed version or just ‘let’s throw a bunch of new characters in there and keep the thing alive.’ It really feels like the next step, and all of our characters, our relationships with one another continue to progress, become more intertwined, more complicated, more meshed. The film has a lot of great comic book moments that the fans are gonna love, but it’s also got a lot of really great dramatic moments that audience members, I think, will really relate to.”
