It's now been more than 20 years since J.K. Rowling's first magical tale of the boy wizard Harry Potter was published, and many of us are still firmly 'neath its spell.

If you, like me, were part of what's known as the 'Potter Generation' - those who grew up in tandem with the books' most esteemed trio, Harry, Ron and Hermione, then you are almost certainly still in the thrall of J.K. Rowling and her nigh-on universally loved creation.

Malfoy and Hermione weren't always so close though, check out this clip:

But once we'd all queued up outside Waterstones at ungodly hours of the morning to be one of the first to buy each book, and ploughed our way through each tale with such alarming speed that outside onlookers would have presumed there was literally a prize for finishing first, we were treated to the Harry Potter movies.

Set over eight installments to cover the seven books, the films are watched and re-watched, and re-watched again by me (and presumably others) many times a year.

And so, perhaps, it's understandable that some fans have become somewhat invested in the real lives of the actors who play some of Hogwarts' most recognisable Alumni.

Rupert Grint, most famous for playing Harry's best friend, Ron Weasley, in the Harry Potter films, has now opened up in a new interview to reveal that he bore witness to "sparks" between Emma Watson (who played Hermione) and Tom Felton (who played Draco Malfoy) on set.

"There was always something (between Watson and Felton)," the 31-year-old actor said, "There was a little bit of a spark."

Per Fox News, he added, "But we were kids. It was like any kind of playground romance".

So while Hermione Granger and Draco Malfoy were about as unlikely to get together as Ron Weasley and one of the massive spiders in the Forbidden Forest, it turns out that Emma Watson and Tom Felton were much more friendly.

However, if their own social media posts are anything to go by, the pair are more than happy just as friends - and long may it continue!
