When will people stop asking Bill Murray if he’ll agree to do a third Ghostbusters movie?

If it seems as though the fan-driven — or has it been media-driven — obsession with including a Ghostbusters 3 question into most interviews and encounters with Murray has gone on for several years, it’s because it doesn’t seem that way. It has been that way. Going back into the 1990s. Co-stars Dan Akyroyd and Harold Ramis, and director Ivan Reitman have said at times, it’s happening; at others, no go. Younger cast replacements. Murray doesn’t want to do it. It’ll happen with or without him. No, wait, we must wait for Murray.

Even David Letterman acknowledged it’s “the tired question” — and he should know because he’s asked Murray about it on his late-night TV show before. Yet Dave and Bill must have agreed to broach the subject again, because broach it they did on Thursday’s episode of Late Show with David Letterman.

While reciting a partial list of Murray’s filmography, Letterman stopped after mentioning Ghostbusters 2 to say: “This brings us to the tired question of what about Ghostbusters 3?”

Murray’s reply this time around?

“You know what? You just really have to have a really good script. You know, it’s hard. I mean, even the second Ghostbusters wasn’t as much fun for me as the first one. You know. It’s hard to make a sequel. It’s got to be really funny. And that first one was so darned funny. It’s hard for me…”

So, Letterman followed up by asking if such a script existed.

“Well, I think we’ll try again. You know, I think. I’ve just been always dragging my feet on it.”

Roll the clip!

The people who like to obsess over a third Ghostbusters should love the fact that earlier and after this part of Murray’s segment with Letterman, they revealed and talked about Murray’s ghost double, who appeared at times in the chair next to Murray on the panel. You can hear just a bit about that at the end of the above clip.

But they should have just stopped after the original classic comedy film. We all can agree on that, right?
