It made its debut in the U.K. capital last Thursday (07Jul11), and Grint admits the screening was so emotional for him he refused to watch the entire movie.

He tells MTV News, "In London, the premiere we've just had, I couldn't sit through it. I caught a bit (of the film). It is really sad.

"There's a scene where all three of us are on the bridge after the battle, the castle is on fire... there's a weird parallel between that and our lives. That always gets me."
