Harry Potter's big anniversary special is just a few days away from premiering, bringing the cast back together to reminisce on the film series and the most magical moments, one of which star Daniel Radcliffe has admitted to being "an absolute dick" about on set.

Daniel, alongside Emma Watson and Rupert Grint, talked about the scene in Deathly Hallows: Part 2 where Hermione and Ron finally kissed after much build-up, a scene Emma described as "the most terrifying thing either of us have ever had to go through".

"It was meant to be this dramatic make out, but [Rupert] and I just kept corpsing and just kept laughing," the actress explained. "I was really scared we were never going to get it because we just couldn't take it seriously."

Daniel interjected, adding: "I did not make this better because I've been told significantly that I was just being an absolute dick about this and was like, 'I'm gonna come on set and watch [Rupert and Emma] kiss'.

"Everyone wanted to be on set for it because everyone was like, 'This is gonna be good guys'," Emma stated. "I knew I was going to have to be the one to make this happen. I needed momentum into the kiss in order to do it... It just felt wrong, so wrong on every level because Dan, Rupert and I are so much siblings. All three of us felt so matched in how much it meant to us."

"I think I blacked out," Rupert said. "I just remember your face just coming closer and closer."

On a similar 'cast feel like siblings' note, Emma Watson has admitted that she "fell in love" with co-star Tom Felton, although nothing happened between them.
