Radcliffe insisted that fame could be overwhelming. He said: "It is totally mad, when people are screaming and going absolutely insane for you. Particularly with Robert - the amount of women that would jump on him - you have to keep it in some kind of perspective, by thinking ''well, partly they like me and partly they are just attracted to the character''.
"As long as you don't think 'oh yeah, God they're all doing this - I must be absolutely fantastic.' As long as you do that, you should be all right," he added.
