Ghostbusters: Every Cameo Ranked From Worst To Best

Role: Martin Heiss

It sort of fits that the most resistant member of the original team would turn up as a world famous debunker and naysayer, who attempts to prove that the Ghostbusters are fake. And an on-form Bill Murray would have been great as the skeptical Heiss.

It's just a shame that an on-form Murray didn't turn up, and that the character - who is as interesting a subplot as Walter Peck was in the original, at least on paper - is under-fleshed, under-used and a little too knowing for his own good. And there's really no need to kill him off: the film pretty much goes out of its way to avoid needless bloodshed (to the point where the climactic "apocalypse" is pretty toothless), him dying sticks out like a sore thumb. Particularly as nobody even seems to bat half an eyelash.
