Bill Murray has been popping up everywhere lately, but with his chilly attitude toward a third Ghostbusters, it was a bit of a surprise to see him show up for a cast reunion. And you can bet he was asked about that sequel. Murray mused fondly about the possibility of a Ghostbusters III, “It’s really hard to recreate something that was so beautiful, so wonderful.” The cast of classic film reunited Monday on The Today Show with host Al Roker, a lifelong fan of the franchise.
