Robert Downey Jr. Confirms Iron Man 4?

Robert Downey Jr. jokingly stated last week that he would return for an Iron Man 4 if his buddy Mel Gibson directed it.  Most took it as an offhand comment but today while speaking during a RedditAMA he had this to say: It was an offhanded remark to a journalist and friend. I have other projects in mind for Mel and I – sooner than later the Marvel Roster will be made public and all questions will be answered.  The actor also appeared on Ellen and said this:

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.”
