10 Exact Moments Actors Died Inside

7. Rupert Grint Can't Look Back On His Hermione Kissing Scene - The Deathly Hallows: Part II

Spending a decade growing up together both on-screen and off of it as part of the Harry Potter world, the reality of having to get a tad intimate with an actor Rupert Grint confessed to having a "brother-sister" relationship with was a tough one to get to grips with by the time The Deathly Hallows: Part II came around.

So much so that the Ron Weasley actor even went on record to admit to PEOPLE, "I never look back at that scene."

After struggling on a number of occasions to keep a straight face in the lead-up to and during the eventual smooch within the Chamber of Secrets late in the day, however, the pair were finally able to keep it together long enough to nail a take.

But as the Potter star would add, after also confessing to the whole awkward scenario being a "very surreal" task:

"One take was enough. It was such a huge moment and there was so much expectation. Quite a lot of pressure actually.”

Emma Watson didn't seem to be in any rush to repeat the experience either, explaining during the Harry Potter 20th Anniversary: Return to Hogwarts special, “Kissing Rupert was one of the hardest things I have ever had to do. It just felt wrong, so wrong on every level because Dan, Rup and I are so much siblings.”
