The Harry Potter films can take several months to complete and with the last two films being filmed back to back, the schedule can be quite grueling. The cast has to endure different kinds of atmosphere thus its no wonder that sometimes they can get sick – they are human after all.

“‘I’m in every day, basically,” Daniel explains when Sky News catches up with him on the set at Leavesden Studios, near Watford. “I was lying in a pool of mud and dust and smoke and it irritated my throat and I developed a cold.”

For Rupert Grint, it can be quite confusing as well.

“It’s getting quite confusing,” laughs Rupert Grint as he takes a break from shooting to talk to Sky News. “We’re kind of mixing them together, and because I’ve got longer hair in the second part I do lose track.”

But both actors agree that Deathly Hallows will be darker and more different than the rest of the Potter films.

“This is gonna have a very different feel to it,” admits Dan. “We barely spend any time at Hogwarts. I’ve been here for eight months and I’ve not filmed a single scene in the great hall, which is unheard of. I’m quite excited.”

At the moment we’ve still got a long way to go,” laughs Rupert, “but it’s gonna be very weird when we hear cut for the last time. But I think I’m ready to move on and see what else there is out there, and get into the real world, really!”
