Robert Downey, Jr was a guest on Jason Bateman’s podcast. During the interview he said he is “done” with the Marvel Universe. As far as I’m concerned I hung up my guns and I’m good to let go. He has been playing Iron Man/Tony Stark since 2008. He is expected to be seen in Black Widow, most likely through flashbacks. He also added, I also think Marvel is on this journey now. They’re trying a bunch of other stuff and you know, I’m excited for them to see how all that goes.
