Freddie Stroma, who plays Cormac McLaggen in Harry Potter And The Half-Blood Prince, talks to UK’s Now magazine about his new fame, Emma Watson, about his muscly and arrogant character, being naked in a movie, and what we would do if he had Harry’s invisible cloak.

There’s a real Internet buzz about you. How does it feel to have thousands of teenage girls chatting about you on the web before the film was even released?
Very strange…It started before I had even done any filming. To have that many people with opinions about you already was quite a shock at first.

Do you find it intimidating or flattering? And how do you stop it from going to your head?
I find it more intimidating really…I’d like to think that at this stage in life you don’t let things like that bother as much as when you’re younger, but it’s still quite scary having that many people expressing their opinion of you, even if it’s only about a picture.

Emma Watson is fast becoming one of the most fancied girls in Britain, what was it like working with her, especially as her possible love interest?
She is an intelligent, talented lady and I enjoyed working with her. She, along with the rest of the cast was really welcoming. I’d like to work with her again at some point.

Cormac is supposed to be pretty big; did you have to do any kind up beefing up for the film?
Not at all. I like to keep in shape but that had nothing to do with the filming. I think David (the director) wanted me to look just the same as I did in the auditions.

He’s also supposed to be a bit of a bad boy, would you say you have a nasty streak in you too that makes you able to relate to him?
Once we started filming the comedy in Cormac became more obvious, so I wouldn’t say that I needed a ‘nasty’ streak to play him. He’s very arrogant and obnoxious but not a particularly evil figure. I’d like to think that there aren’t a lot of similarities between Cormac and I, I base a lot of my acting on behaviour I’ve seen in other people.

In his theatre role for Equus, [Daniel] Radcliffe got his kit off, would you ever consider going nude for a role? Hmm… I suppose I would yes, depending on whether it was tastefully done…

If you had Harry’s cloak for one day what would you do?
I would go into the offices of the hard-working men and women of London and throughout the day steal/move stationary from their desks. I would probably grab a free lunch while I was there…
