The actor has said that kissing was an unnatural thing to do with Emma Watson. Rupert Grint, who knows her since she was nine, took some time before getting into the scene. He adds that they put their friendship aside before the smooch scene.
“It's quite full-on, a proper snog. We're soaking wet as well - they dumped gallons of water on us and then we just went for it. We laughed a lot and it took us a while to concentrate. We did it about four times," the Contactmusic quoted him as saying.
He concluded that they are really good friends and she is like his sister. However, they are playing the roles of Harry Potter's friends in Harry Potter and the Deathly Hallows – Part 2, which will hit the screens on July 13 and 15 in the UK and the US respectively.
