Dan Aykroyd and Bill Murray

In the new Ghostbusters reboot (sequel?), Kristen Wiig, Kate McKinnon, Leslie Jones, and Melissa McCarthy will star. Additionally, Chris Hemsworth has been cast in a role. But two more actors are confirmed to have cameos in the movie. They are, of course, two actors from the first two Ghostbusters films, Dan Aykroyd and Bill Murray. Unfortunately, there will be no appearance from Harold Ramis, obviously, which I think is part of the problem this ill-fated movie. It's not even said whether or not they will be playing their characters from the original movies. I just don't know...
