Is Hugh Grant’s Most Convincing Character ‘Hugh Grant’? Is Hugh Grant’s Most Convincing Character ‘Hugh Grant’?

The seemingly droll, breezy star is actually sentimental about his family and utterly serious about his work, including his villainous turn in “Heretic.”

Hugh Grant has been suffering from brand confusion since 1994, when his performance in “Four Weddings and a Funeral” established him as a quintessentially British romantic hero of winning charm and diffidence. But his recent run of strange and sometimes creepy characters plays so effectively against type that you begin to suspect you were mistaken about his type all along.

He would be the first to say that something darker and more complicated lurks beneath his easy surface.

“At school I had a teacher who used to take me aside and say, ‘Who is the real Hugh Grant? Because I think the one we’re seeing might be insincere,’” Grant said as he strolled through Central Park last month. He was comparing himself — or at least his powers of persuasion — to Mr. Reed, the charismatically articulate villain he plays in “Heretic,” a religious-horror movie due in theaters on Nov. 15. “The ability to manipulate and sort of seduce — I might be guilty of that.”

At 64, Grant is enjoying what he calls “the freak-show era” of his career, playing an unlikely rogue’s gallery of suave miscreants (“The Undoing,” “A Very English Scandal”), seedy gangsters (“The Gentlemen”), power-hungry tricksters (“Dungeons & Dragons: Honor Among Thieves”) and self-deluded thespians (“Paddington 2” and “Unfrosted”), not to mention the bumptious little Oompa-Loompa in “Wonka.” That abashed, floppy-haired, benign early version of himself — that was never who he was anyway, he says.

“My mistake was that I suddenly got this massive success with ‘Four Weddings’ and I thought, ah, well, if that’s what people love so much, I’ll be that person in real life, too,” he said. “So I used to do interviews where I was Mr. Stuttery Blinky, and it’s my fault that I was then shoved into a box marked ‘Mr. Stuttery Blinky.’ And people were, quite rightly, repelled by it in the end.”

Grant had just come from Toronto, where “Heretic” had its premiere. In New York it was a blazingly beautiful day, and he greeted the park like an old friend, passing some of his favorite landmarks: the Delacorte Clock, whose bronze animals were doing their delightful dance to music to mark the hour, and the statue of Balto, the heroic medicine-transporting Siberian husky posing imperiously on his rock not far from the children’s zoo.
