When Robert Downey Jr. appeared on Jimmy Kimmel Live on Tuesday night, Jimmy Kimmel grilled the Iron Man star on if there was going to be an Iron Man 4. Robert Downey Jr. said, “Well, you know the funny thing is you have this kind of weekend, and then instantly Monday morning, you think there’s going to be the next announcement."

Robert Downey Jr. continued, “But I mean the economy really is weird, and I was thinking if we were going to do another one we would maybe tentatively call it Iron Man 4. But I wasn’t getting a lot of support, so I decided to…buddies told me there’s a Kickstarter thing. So as of now if you want to see a sequel, please go to Kickstarter.com and put in your vote.”

Jimmy Kimmel said, “Oh, so you’re raising money, wow, alright, I will kick in something for that.” Robert Downey Jr. added, “Every little bit helps.”

Later in the show, Jimmy Kimmel said, “You don’t know this yet, but very exciting, we just got some figures in, and Robert’s Kickstarter campaign, we’ve already got $1.8 billion pledged. Wow, so now you have to do another one.” Robert Downey Jr. responded, “Yeah, I don’t know, is that enough?”

After the Kickstarter joke, Jimmy Kimmel asked Robert Downey Jr. if he would seriously think about doing another one. Robert Downey Jr. replied, “Yeah, it’s been one of the best things in my life professionally, and people really like it.”
