Fans posing with a person in a Spider-Man mask at the Comic-Con convention in America may actually have been standing next to Harry Potter.
Daniel Radcliffe, who played the boy wizard in the on-screen adaptations of JK Rowling's fantasy book series, has said he donned a Spider-Man mask at the San Diego event this weekend in order to make his way through the crowds unnoticed.
In an interview Radcliffe said it was a great experience.
"I did an American accent for the whole time," he said. "I even took a rucksack, so I look like I'm just coming to Comic-Con. I had a whole look. But it was great ... I took lots of pictures with people who did not know that it was me."
The 25-year-old said he was delighted to become his favourite superhero character for a few hours during his first ever appearance at the convention.
"I always loved that character. I love the comics, actually, as well," he said. "I almost got a picture with two girls dressed as Mary Jane and Gwen Stacy, but the moment had passed."
Radcliffe's latest film Horns sees him play a character who sprouts horns on his head that are invisible to others but provoke them to confess their darkest truths to him.
