Bill Murray has been spotted on the set of Ghostbusters 2020, so it would appear that he may be in Ghostbusters 3 after-all. However, he seemingly only appeared in the final stages of the shoot, so how much screen-time he will get remains to be seen. This isn’t the first time Murray has proven has proven to be something less than reliable, and his reluctance to reprise his Ghostbusters role of Peter Venkman has caused several past incarnations of Ghostbusters 3 to flounder. Why is this? What caused such animosity between him and the Ghostbusters brand. That is what we will look into, in this video.
