20 Essential Movie Moments That Will Define 2016

The Moment: Bill Murray's much-discussed cameo, playing not his original character Peter Venkman, but a new creation altogether, a skeptic of the spirit world who attempts to debunk the paranormal madness descending upon New York City.

Why It Will Define 2016: Whether the cameo ends up being a fun nod or a disgustingly on-the-nose failure, there's zero chance of it being quickly forgotten. For better or for worse, people will be talking this one up for a long time, and considering how long it's taken to get Bill Murray in another Ghostbusters movie (no matter the circumstances), it's pretty much destined to be instantly iconic either way.

And of course, there's definitely part of us that still hopes he's playing Venkman, and it's all a big troll. Fingers crossed.
