Julianne Moore Digs Into a Box of Lies With Jimmy Fallon (Video)

The Oscar-winning actress fakes out the late-night host with the help of an Oscar the Grouch toy wearing Donald Trump’s “Make America Great Again” hat

Julianne Moore has proven she can act countless times, including with her Oscar-winning “Still Alice” performance, but can she lie better than Jimmy Fallon?

“Tonight Show” viewers found out on Tuesday when the actress went head-to-head with Fallon in a game of Box of Lies.

“Each player selects a box out of view of the other person,” Fallon explained. “You show it to the audience then look at your opponent and tell them what’s in your box … you might be lying, you might be telling the truth.”

A squeaky-voiced Moore slipped easily into the role of liar when she faked out Fallon with her description of a “super soft garbage can with Oscar the Grouch,” which happened to be wearing a Donald Trump “Make America Great Again” hat.

Fallon then fooled Moore into believing that “a naked Justin Bieber doll in rollerblades” was actually a book made out of macaroni.

But even he was surprised when the “Map to the Stars” actress pulled out a photo of the pair of them taken earlier in the show.

“The Tonight Show” airs at 11:35 p.m. ET on NBC.
