Daniel Radcliffe thought shaving his head would make him more anonymous.
The 27-year-old actor - who shot to fame playing Harry Potter in the movie series - underwent a dramatic change of appearance for his role as an FBI agent who goes undercover with a gang of white supremacists in his new movie Imperium and found the drastic change of hair cut made no difference to the number of fans who spotted him in the street.
He said: "Unfortunately shaving my head did not make me less recognisable.
"I would have thought that as well but unfortunately it seemed to.
"My hair gives me a little bit of cover and I think without my hair I'm just a big pair of eyes, and people recognise me from my eyes anyway, so that might not work."
Daniel also expressed his desire to return to the stage in a musical, though insisted he has no desire to show off his dance moves on a show such as Strictly Come Dancing or Dancing With the Stars.
Speaking at a gala screening of Imperium and his other new movie Swiss Army Man at the opening night of Empire Live at London's The O2, he said: "No, I would not go on Strictly. I love dancing and I'd love to do another musical at some point, but live every night, in front of the nation, every week? No."
And Daniel - who plays a flatulent corpse in Swiss Army Man - also joked he'd be interested in the vacant presenting slot on The Great British Bake Off when it changes networks from the BBC to Channel 4 next year.
He said: "Host the new Bake Off? Ok. Yeah, great... so it will be me, my corpse dummy and Paul Hollywood doing some baking. I wouldn't be able to bake, but I would be there in support."
