Ew.com reports that even Rick Moranis who played the gate keeper Louis Tully will also return to the Ghost Busters III cast.

… And yes, the original cast will return: Dan Aykroyd, Ernie Hudson, Rick Moranis, and even the elusive Bill Murray. “Everybody said they’d do it,” says Ramis, who doesn’t intend to direct Ghostbusters III. “They’ll be looking at younger actors [for the lead roles], I’m sure. But we’ll be in it as mentors or advisers. I think the first one captured something that hadn’t been seen for a long time: the combination of scary movies and smart broad comedy. That was a great comic edge to play. Fortunately, we stopped before we beat it into the ground. If we’d done a third one then, no one would want to see one now, I think, cause we were headin’ downhill, even with the second one,” he laughs. “We’ll see, everyone’s gonna have to love the [Ghostbusters III] script to move it forward.”
