Warning: This video contains some explicit language ... but is absolutely hysterical!

Julianne Moore is really showing off her acting chops!

The Oscar-winning actress appears in a new episode of "Billy On The Street," where she and Billy Eichner run around NYC and ambush random tourists with her acting abilities ... with the hopes of making a few extra bucks.

Check out the hilarious video above to see how Moore does!

The duo first stop one unsuspecting Aussie for a quarter, and Julianne immediately breaks into character while reciting a line from "The Kids Are Alright."

"The bottom line is: Marriage is hard," Julianne reads from a note card, while welling up with tears. "It's really f---ing hard."

Next, for two bucks from two nice ladies, the 54-year-old acts out a scene from "Magnolia."

"You f---ing a--hole!" she shouts. "Who the f--k do you think you are? You don't know who I am, you don't know my life, and you have the balls and decency to ask me questions about my life? F--k you too! Don't you call me lady!"

We love how people ran up to take selfies during the intense moment!
