A profile of actor Daniel Radcliffe, who, despite becoming wildly famous at a young age after he starred in the Harry Potter films, has managed to stay earnest, self-aware, and out of the tabloids:

“Rupert Grint, who played Ron Weasley, Harry Potter’s best friend, recently described the long, drawn-out experience of appearing in the films as ‘quite suffocating.’

“Radcliffe, however, rarely betrayed any strain. ‘If he was feeling good, bad, indifferent or terrible,’ says David Yates, who directed the last four Potter films over six and a half years, ‘he carried the perception that everything was lovely and great, even though the pressures were really intense.’

“As Radcliffe explained it: ‘The second you seem down, everyone’s very concerned. It affects the set.’ Temporarily suppressing a mood was easier than bringing a crew of hundreds of people to a halt — it was just another skill he learned on the job, part of keeping the vast machinery around him moving smoothly. ‘If I ever was feeling ill,’ he said, ‘it was: “Get a doctor on set!” “No, I’m fine.” … That feeling makes me not want to worry people.'”
