Many people seem to have forgotten what a vampire is, so I'm going to provide a very brief primer that you can reference when in doubt.

Before I get an angry tsunami of vampire aficionados (unlikely, due to readership) admonishing me for my choices, let me stress that this is a short list of accessible examples and by no means definitive.  These aren't necessarily my favorite vampires or vampire movies either, but I'll go to the mat for the underrated Bram Stoker's Dracula.

Here it goes...

This is a vampire:

Gary Oldman in Bram Stoker's Dracula

This is a vampire:

Max Schreck in Nosferatu

This is a vampire:

Lina Leandersson in Let the Right One In

This is a vampire:

Dick Cheney in real life

Even these two are vampires:

Tom Cruise and Brad Pitt in Interview with the Vampire

This is an understudy for an Acqua Di Gio commercial:

Robert Pattinson in Twilight

That is all.
