Robert Downey Jr. Confirms Iron Man 4?
So he seemingly confirms Iron Man 4 will happen and says we will know more soon. Stay tuned.
And for those interested in the next Sherlock Holmes film, Downey Rr. said this during the Reddit chat: Yes, we have a Sherlock 3 in development. We want it to be the best of the series, so that’s a pretty tall order. Also, Perry Mason is a property I’m looking forward to developing further, going back to the 1931 book series…similarly to what we did with the first 2 Sherlocks, mining the original material for things that are “new.”
