Nicolas Cage has spoken on the vampire photo of him that made headlines last September. It's a somewhat slowed down version of me, the Ghost Rider actor told David Letterman Thursday. (PHOTO: Screen Capture / CBS / David Letterman).

Nicholas Cage is not from the 1800s. He's also not a vampire.

The 48-year-old actor has finally spoken about that photo of his Civil War-era twin that popped up back in September.

I've heard about it, yeah, Cage said on The Late Show with David Letterman Thursday night.

Let me say that there is resemblance, but, how can I be polite about this? It's a somewhat slowed down version of me . . . it's slowed down, he said, as the program showed a split screen image of Cage and his twin from two centuries ago.

Last September, an eBay seller posted the photo for sale, with an asking price of $1 million.

Personally, I believe it's him and that he is some sort of walking undead/vampire, etcetera, who quickens/reinvents himself once every 75 years or so, the seller, Jack Mord, wrote in an eBay description.

150 years from now, he might be a politician, the leader of a cult or a talk show host . . . my theory is that he allows himself to age to a certain point, maybe 70, 80 or so, then the actor 'Nicolas Cage' will 'die' . . . but in reality, the undead vampire 'Nicolas Cage' will have rejuvenated himself and appeared in some other part of the world, young again, and ready to start all over, the description continued.

Cage was visiting the Late Show on Thursday to promote his latest film, Ghost Rider: Spirit of Vengeance, the sequel to 2007's Ghost Rider. That year, the film went on to gross more than $228 million at the box office worldwide.

But back to the vampire photo.

Look, I don't drink blood and last time I looked in the mirror, I had a reflection. So I'm not going with this vampire theory, I'm just not gonna do it, Cage told Letterman.
