Tom Felton reacts to one ‘Harry Potter’ line delivery that became iconic

Tom Felton opened up about his most timeless dialogue delivery and how unexpectedly it became fan-favourite.

Felton is known for his role as Draco Malfoy, the antagonist of the Harry Potter series opposite to the titular hero played by Daniel Radcliffe from 2001 to 2011.

Malfoy was a sneering Slytherin student, who was raised in a pure –blood supremacist family and looked down on people like Harry’s friends , Ron Weasley (Rupert Grint) and Hermione Granger (Emma Watson).

In addition to that, Draco had grudge and hated the lead character when Harry turned him down and choose Ron instead as his best friend, bruising Draco's ego.

Since then he began calling the Gryffindor student by his sir name, "Potter" in venomous slur like way.

In his appearance at the recent podcast episode of Happy Sad Confused with Josh Horowitz, the Murder in the First actor expressed his amazement saying, "I don't know how that's become an iconic thing. I certainly had no idea."

Sharing from where the idea of delivering the pronunciation in a unique way came from, he added, "I have three older brothers, so they all would always call me something like maggot or what was I also called? Runt. Runt of the pack."

"Because I was the youngest and the shortest considerably. So I don't remember ever thinking about it for a second," he further explained. "But 'Potter,' it just got more and more venomous."

Sharing his experience of saying it in company of the franchise fans and the reaction is always either "goose bumps and, like, applause, something happens."

Felton is back into the shoes of Draco Malfoy, by starring in Broadway version of Harry Potter and the Cursed Child, which is set 19 years after Deathly Hallows and follows the next generation of wizards.

Meanwhile, Harry Potter TV series is also set to premiere on Christmas, on HBO Max.

Starring Dominic McLaughlin (Harry Potter), Arabella Stanton (Hermione Granger), Alastair Stout (Ron Weasley) and Lox Pratt (Draco Malfoy).
