Filming for the new Harry Potter movie is so intense, it has left Daniel Radcliffe nursing a nasty cold.
The 20 year old is busy working on the final franchise installment, Harry Potter and the Deathly Hallows, which is being split into two films.
The story sees Radcliffe and co-stars Rupert Grint and Emma Watson's characters on the run - and the harsh filming conditions have made the actor sick.
He tells Sky News, "I'm in every day, basically. I was lying in a pool of mud and dust and smoke and it irritated my throat and I developed a cold."
