Jimmy Fallon Says This Celebrity Was His "Most Awkward" Interview Ever

Fallon handpicked the star to be his first guest.

During an appearance on Watch What Happens Live in December of 2011, a caller asked Fallon what his most awkward interview ever was. Fallon revealed that it was Oscar-winning actor Robert De Niro, who was a guest for his March 2009 debut as the host of Late Night. Andy Cohen noted that De Niro is known as a "notoriously kind of difficult interview."

"Yeah, in real life he doesn't even talk much," Fallon responded. He went on to explain that booking guests for a new talk show isn't easy because publicists are hesitant to put their clients into a situation where they don't know what's going to happen. So Fallon had to be strategic about asking someone who would agree to do the show.

"So I was like, 'I want to get somebody A-list,' and I want someone in New York," Fallon continued. De Niro was the first name to come to mind.

Fallon said he'd done some charity work with the Taxi Driver star, so he felt comfortable asking him. "And here's the coolness of Robert De Niro," the host went on. "He didn't have a movie coming out, had nothing to promote, he said, 'Absolutely, yes," as soon as I asked him."

Fallon's first interview with De Niro was awkward for one specific reason.

His first interview with De Niro was stressful, Fallon said, because the star would only give "one-word answers." Doing an impression of the actor, Fallon illustrated how he would only say "yup" and "nope" to his questions.

Fallon also told Cohen that throughout this interview with De Niro, he was feeling very nervous, and it showed.

"It's flop sweat coming down my face," Fallon said. "My hair looked like it had a comb-over...At one point I was delirious, I couldn't even see him...I was just getting loopy, but he's the best."

De Niro played a prank on Fallon before he came onto the show.

There are no hard feelings between De Niro and Fallon, and, since Fallon took over as host of The Tonight Show, De Niro has come onto the show a few times. During an April 2018 appearance, Fallon revealed that the actor played a prank on him when they were planning that infamous 2009 Late Night interview.

The host recalled that De Niro's publicist had asked Fallon to email De Niro his questions ahead of time. "I sent the questions, like 15 questions to you, and you go, 'Pretty good, what else you got?'" Fallon said to his guest. He then explained that he sent another 15 to the same response, and then another, and so on.

"Now my questions are getting bizarre," Fallon laughed. "And as I'm typing, I got an email from you that goes, 'Ha ha, just kidding. See you on the show.'"

Fallon and De Niro have laughed about the interview a lot over the years.

During a 2015 Tonight Show appearance, Fallon brought up the "favor" he'd asked of De Niro back in 2009.

"I gotta say, I had no idea what I was doing," he said of that first episode and rough interview. "I ran out of questions to ask you because you don't even like doing talk shows that much."

De Niro clarified that he didn't mind doing talk shows, depending on host, and assured Fallon that he'd done "a great job."
