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.

"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."
