If Rupert Grint could forget about kissing “Harry Potter” co-star Emma Watson, he would. The 27-year-old English actor has shared his struggle to shoot a momentous Ron Weasley and Hermione Granger scene, saying he can’t remember anything about the kiss.

“I never look back that that scene,” Grint, 27, told People magazine on Friday. He was at the Universal Orlando in the US for a three-day celebration of “Harry Potter.”

“I’ve known Emma since she was literally 9 years old and we had this very brother-sister relationship,” he continued. He was referring to the famous kissing scene of Ron and Hermione in “Harry Potter and the Deathly Hallows Part 2,” wherein Harry’s best friends finally fully realised their feelings for each other.

“And it just felt very surreal. I have a memory of her face getting closer and closer. Like, ‘Oh my God.’ I can’t really remember anything apart from that.”

This isn’t the first time Grint talked about the scene. He and Watson were repetitiously interviewed about it in 2009 when they were promoting the film.

“Neither of us were looking forward to it,” Grint told Movies Ireland, adding that shooting the scene was “weird.”

Watson, 25, agreed. She described the ordeal as “honestly like kissing my brother.”

When asked if the scene took five takes to perfect because Grint was maybe deliberately messing it up so he could keep kissing her, Watson was emphatic in saying they both wanted it to end immediately. “We both wanted it to be over equally as much as the other,” she said.

Daniel Radcliffe, who played the title character in the multibillion film franchise, basically also said the same thing. He also had a kissing scene with Watson in the first part of “Deathly Hallows.”

“It was kind of weird. It is a bit like kissing your sister,” Radcliffe, 26, told MTV News in 2010. He added, however, that he was not complaining because the kiss was “good” and “vigorous.”

Watson was proud of the kiss because it did not appear awkward when it was anything but when they filmed it. She had to kick Grint out from the set while they were shooting it, though, because Grint kept laughing.

“When they were there actually filming that kiss, they did actually want me there to kind of play off something, but I just found that too funny,” Grint was quoted by as saying.

The oldest of the trio recently confirmed an old rumour about the cast. “Yeah, that is true,” he told the Huffington Post about the claim he did not do an essay assigned by director Alfonso Cuarón, while both Radcliffe and Watson did.
