In an interview with Vulture, Murray talked about what convinced him to make the Ghostbusters reboot cameo in the first place:
“You know, they were incredibly nice to ask me, and I really enjoyed being there. They have such a jolly group, and they are going to have great success with this project. I didn’t want to overshadow [them] or anything, and I feel really good about it.. I like those girls a lot. I mean, I really do. They are tough to say no to. And Paul is a real nice fellow.”
“I thought about it for a very long time. Like, many, many months. No, that’s not right. I was seriously thinking about this for years, really … It kept eating at me, and I really respect those girls. And then I started to feel like if I didn’t do this movie, maybe somebody would write a bad review or something, thinking there was some sort of disapproval [on my part].”
Ghostbusters will open in U.S. theaters on July 15th, 2016.
