Bill Murray will be seen in the upcoming Ghostbusters rebootColumbia Pictures

The original Ghostbusters (1984) star Bill Murray seemed pretty sure about not starring in part 3 of the hit franchise. Despite many attempts and several script rewrites, Murray refused to come on board. It was certain that the actor was done with that role.

However, he did not hesitate to appear in Sony's all-female remake/reboot, when director/co-writer Paul Feig came knocking. "One of the reasons he did it, I think he liked the role we wrote for him," Feig told Yahoo Movies. (via ComicBook.com)

"But he also just likes these actors, and just wanted to be a part of it. And he didn't want to give any stamp of disapproval by not coming on board." Talking about having Murray on sets, Feig said, "It was really nerve-wracking, and special."

The director also spoke about how Murray showed off his well-known improvisational skills, while shooting for a scene. "As he was doing this role we wrote, he did this one take in particular where like, in Meatballs, where he just bursts out with some big thing," Feig recalled. "It wasn't scripted. That's when you're like, 'Oh my God, wow, Bill Murray's here',"

Ghostbusters makes its long-awaited return, rebooted with a cast of hilarious new characters. Thirty years after the beloved original franchise took the world by storm, director Paul Feig brings his fresh take to the supernatural comedy, joined by some of the funniest actors working today – Melissa McCarthy, Kristen Wiig, Kate McKinnon, Leslie Jones and Chris Hemsworth.

Ghostbusters is slated to release on 15 July 2016.
