If this is your first encounter with Robert De Niro, welcome to Earth. We hope the spaceship you crashed in isn't too wrecked.

The Oscar winner, who's premiering his latest film The Family today, has not only become a legend for his impressive body of work—Raging Bull, The Godfather II, GoodFellas—but for his signature face. Facial expression, really. It's the one where he contorts in a way that makes it look like he just ate something super sour and super disgusting, yet curiously delicious at the same time. It's something so particular to him that other entertainers admire it, even inadvertently, as much as they look up to his career. 

The proof is in the pictures: Celebrities Doing the Robert De Niro Face.
