With sporadic updates on Ghostbusters 3 in recent years, the last we heard is that the film would be put on hold due to rumors that Bill Murray would not lend his involvement thanks to the script. Murray has obviously the odd man out when it’s come to this sequel so far, and he’s also remained the least vocal of those involved within the supernatural comedy franchise. Moonrise Kingdom hit theaters just a couple weeks ago, and has been expanding to more markets as the buzz has grown, with the actor being a part of the impressive ensemble. Now, Murray was a guest on the David Letterman show to promote the film, and was asked about the possibility of a sequel to the famous 80s comedy. His response? Surprisingly just a bit positive.

In an interview on Late Show with David Letterman, the titular host ran through some of Murray’s classic films and when asked whether or not a third Ghostbusters was in the works, Murray replied “You know, you just have to have a really good script. And it’s hard…even the second Ghostbusters wasn’t as fun for me as the first one. It’s hard to make a sequel. It’s got to be really funny and that first one was so darn funny, it’s hard for me…”

When asked if a script was currently in development, Murray said “I think we’ll try again. I always drag my feet on it, but I think…” It’s there that Letterman unfortunately cuts Murray off, tying in a previous joke instead of letting the comedic actor finish his thought.

Here’s the full segment:

Dan Aykroyd and Harold Ramis have been working on a script for awhile now, and after Murray’s rejection of what seems like multiple drafts, they effectively stopped trying for the time being. Murray obviously has high expectations for a sequel and doesn’t want to simply do a third Ghostbusters for the sake of it. While he doesn’t seem completely sour to the idea in the interview above, it’s clear that he wants something more than what Aykroyd and Ramis have come up with so far and it needs to be something that not only convinces him to do another installment but also convinces the fans that it’s worth it.
