Watch Ghostbusters' Bill Murray Interrupt Jimmy Fallon's Monologue - and Show Him How to Use a Proton Pack

The opening monologue is a key segment of The Tonight Show Starring Jimmy Fallon, but there's no time to waste when ghosts are lurking around.

That must've been what Saturday Night Live legend Bill Murray was thinking when he interrupted Host Jimmy Fallon's monologue during the March 15 episode. Murray was joined by fellow original Ghostbuster Ernie Hudson to promote the franchise's newest installment,emGhostbusters: Frozen Empire/em./p p"I think it's more important that people here find out a little more about the new emGhostbusters/em movie," Murray told Fallon after he ran out from behind the curtain./p pFallon agreed, but as the two walked over to Fallon's desk to start the interview, Murray realized he was missing Hudson. So he enlisted some audience volunteers to help find his fellow Ghostbuster, who turned out was still getting ready in the makeup chair backstage./p pa data-entity-href="https://www.nbc.com/nbc-insider/the-tonight-show-guests-this-week" data-entity-title="https://www.nbc.com/nbc-insider/the-tonight-show-guests-this-week" href="https://www.nbc.com/nbc-insider/the-tonight-show-guests-this-week" target="_blank" rel="noreferrer noopener"strongRELATED:Who's on The Tonight Show Starring Jimmy Fallon the Week of March 18?/strong/a/p pAfter hustling Hudson onstage for their interview, Fallon asked them if they knew the first emGhostbusters/em was going to be a hit back when it was released in 1984./p p"I actually did," Murray revealed. "We went to Thanksgiving dinner at the director Ivan Reitman's house, and he showed us an early cut of the first scene of capturing the first ghost. And it was so extraordinary that when we went back to work on Monday, the crew was like, 'We're ready.' And I was like, 'Relax everybody. We've got a big one here. We can all take our damn sweet time now. This is gonna be good.'"/p div data-embed-button="media" data-entity-embed-display="view_mode:media.embed" data-entity-embed-display-settings="[]" data-entity-type="media" data-entity-uuid="eadd661e-a921-4dd7-85a2-6d00606fdd9c" data-langcode="en" class="embedded-entity"div class="media__image" style="max-width:862px" div class="media__image-wrapper" div div img loading="lazy" decoding="async" fetchpriority="low" src="https://www.syfy.com/sites/syfy/files/styles/scale_862/public/2024/03/the-tonight-show-bill-murray3.jpg" width="862" height="575" alt="Actor Bill Murray interrupts the Tonight Show monologue on Friday, March 15, 2024." typeof="foaf:Image" /div /div /div div class="media__metadata" div class="media__metadata-wrapper" span class="media__caption" Actor Bill Murray interrupts the Tonight Show monologue on Friday, March 15, 2024. /span span class="media__credit"Photo: Todd Owyoung/NBC /span /div /div /div /div pHudson didn't think it was going to be big until he watched an early screening of the first film./p p"Bill knew, but the first time I saw it with an audience, something happened in the very beginning when Bill was interviewing the couple, something came over the audience," he recalled.
