Indiana Jones fansite The Indy Experience shares a few quotes from an interview between George Lucas and Time Magazine: "You know, I said three’s fine. And then I came up with an idea I thought was brilliant, so I told the other guys (Steven Spielberg and Harrison Ford), and they kind of flipped out …
It’s vaguely in the realm of the supernatural. We have to accept the fact that Indiana Jones is an older man. But it’s been hell getting a script out of it. Steven is committed to shooting it next year. I just got the latest script yesterday." So while a lot of things could pop up between now and "next year," it does seem fairly realistic to expect a fourth Indiana Jones adventure within the next few years. (Gee, where have we heard that one before?)
