4. Harold Ramis' Posthumous Cameo - Ghostbusters
In one of the controversial reboot's very first scenes, Erin Gilbert (Kristen Wiig) has a conversation with the Dean of Columbia University's Physics Department, Harold Filmore (Charles Dance).
As he leaves the room at the conclusion of the chat, the camera lingers for a beat on a bronze bust of a very familiar figure. Of course, it's a statue of the inimitable Egon Spengler, a neat way of giving Harold Ramis a cameo in the movie alongside his Ghostbusters compatriots Bill Murray, Dan Aykroyd and Ernie Hudson despite the fact Ramis died in 2014.
Though many of the movie's nods to the original border on cringe-worthy or desperate, this one's flat-out awesome.
