Avengers: Age of Ultron will be in theaters this weekend, and soon all eyes will instead be pointed towards Marvel's next superhero adventures Captain America: Civil War, Avengers: Infinity War Part 1 and Avengers: Infinity War Part 2. All three impending blockbusters will be directed by Joe Russo and Anthony Russo. Clearly, this is not a job for one man. While many were surprised that Joss Whedon refused to return for the continuing adventures of Earth's mightiest warriors, those close to the project weren't. Especially Robert Downey Jr. While he might be sad to see his former captain go, he has full faith in the new guys. About Joss Whedon's departure, he says:

"I wasn't surprised because there was so much onus on can [Avengers: Age of Ultron] be as good as Avengers Assemble? I just think it takes so much out of the men and women who are behind the major workload that occurs over a 24-month period, at best, to get one of these movies done. It's backbreaking."

Robert Downey Jr. has yet to shoot a movie with the Russo brothers. But that will soon change, as he spends most of 2016 and 2017 with the two siblings, who have clearly made their mark on the MCU. Captain America: Civil War is gearing up to shoot in the next few weeks, and should take the team through summer. Then Avengers: Infinity War Part 1 and Avengers: Infinity War Part 2 will be shot back-to-back over the course of 9 months leading from late 2016 into fall 2017. After which, Robert Downey Jr.'s future with Marvel remains uncertain. About his new directors, he confidently states:

"Its different every time. I'm also a very kind of loyal person so sometimes there's a new face and I'm like 'Wait a minute.' But the interesting thing is I've worked with Jon twice, I've worked with Joss twice, and I worked with Shane Black once-and I'd happily do it with any of those three folks again. I really think the Russo Brothers are super sharp and I think they are worthy stewards of carrying it forward."
