Daniel Radcliffe recalls nervously meeting Donald Trump, and the advice he gave him

Daniel Radcliffe reveals that he got some advice from Donald Trump back when he was just gaining notoriety for his leading role in the Harry Potter films.

On Monday's Late Night With Seth Meyers, the 26-year-old actor revealed that he met the presidential hopeful backstage when they were both guests on the Today show. Radcliffe, who was promoting Harry Potter and the Sorcerer's Stone at the time, was nervous about appearing on the morning show, as it was all new to him.

Prior to his appearance on Today, he met Trump. "They marched me over to him, and I remember having some idea of who he was but not really a full concept," Radcliffe recalled, adding that he admitted to the business mogul that he was nervous about his TV interview. "He just said, 'You just tell them you met Mr. Trump.'"

Radcliffe quipped that it was a piece of advice he'll never forget. "To this day, I can't even relate to that level of confidence," he said. "Imagine if I said, 'Oh, just talk about me during your interview.' Like, I'm interesting enough to be everyone's story."

Radcliffe told his tale just a week after Meyers announced that Late Night had banned Trump from coming on the program, after the 70-year-old aspiring politician revoked the Washington Post's press credentials. "As for the Washington Post, we here at Late Night believe in freedom of the press and therefore have decided to stand in solidarity with them," he said. "So as long as the Washington Post is banned from Donald Trump's campaign, Donald Trump will be banned from ever coming on this show."

Trump responded to the ban by saying that Meyers has been "begging" him to appear on Late Night. "I only like doing shows with good ratings," he said in a statement released by his campaign. "Which as everybody knows, I only make better (by a lot)."
