For Ghostbusters day — the anniversary of when the movie was released in 1984 — Jimmy Kimmel celebrated by getting both the new and old cast together to hang out together on his show. Bill Murray, Dan Aykroyd, Ernie Hudson, Annie Potts, Melissa McCarthy, Kristen Wiig, Kate McKinnon and Leslie Jones all united on Jimmy Kimmel Live last night to chat about the movie(s) and dance together as Ray Parker Jr. played the theme song live.

To put it mildly, 2016's Ghostbusters has been surrounded by controversy including silly "you're ruining my childhood!" claims and outdated complaints that women shouldn't be ghostbusters. But the O.G. Ghostbusters have the women's backs, the movie looks great, and everyone seems to be having a great time in the clips below.
