While most buildings have plenty of windows to look out of or into, this on in downtown Manhattan appears to have none at all.
As always, internet users were eager to provide the film star with some more information about the picture.
One user said: "The old ATT building famous for being windowless aaand you don't wanna know what goes on inside."
The building is also reportedly designed to survive nuclear fallout.
