One of the most beloved properties still going strong today is Harry Potter, a phenomenon that has continued to captivate audiences for decades following J.K. Rowling’s initial book releases. A significant factor contributing to its enduring popularity can be attributed to the highly-acclaimed Harry Potter films, which many people enjoy repeatedly watching or streaming via services like Max. Notably, Jason Isaacs portrayed Lucius Malfoy in these movies, and recently shared why he almost employed the killing curse against Harry in The Chamber of Secrets.
As enthusiasts of the Wizarding World eagerly anticipate updates on the upcoming Harry Potter television series, tidbits about the movies continue to surface. Lately, actor Isaacs made an appearance at Fan Expo Denver (as reported by Collider), and he divulged the authentic rationale behind his character’s initial use of “Avada Kedavra” towards Harry prior to being halted by Dobby. In his own words:
During our conversation, there was a moment when I found myself in a situation where I was supposed to cast a spell. Someone suggested that I should begin, but I panicked, thinking ‘I don’t know any spells!’ So, I looked around for help and spotted a crew member adjusting the lights, caterers, someone holding a microphone, and another individual. This person informed me that there was indeed a spell, called Avada Kedavra. A year later, when the movie premiered, I received over 100,000 letters from people who were surprised because they thought I was trying to kill Harry Potter!
It seems that, while filming his debut as Lucius Malfoy in “Chamber of Secrets”, Isaac wasn’t particularly knowledgeable about Harry Potter at the time. This lack of familiarity led to him unintentionally mispronouncing a spell during the movie, which sparked a lengthy discussion among Potterhead fans about the correct pronunciation of the killing curse.
Initially, the characters from the “Harry Potter” series may seem legendary today, but in reality, they were simply actors performing their roles. Isaac, indeed, proved an excellent selection for portraying Draco’s father, despite the initial challenges he faced while mastering the character.

The Harry Potter series is currently streaming on Max at a monthly cost of $9.99 for the ad-supported tier. With three different plans to choose from after subscribing, you also have the option to prepay annually and receive a 20% discount. Check out the deal now!
During the filming of the Harry Potter series, Jason Isaacs and Tom Felton developed a strong bond. This friendship started during the production of The Chamber of Secrets. At a subsequent convention, the star of The OA playfully mentioned that he felt rather ‘green’ in the magical world at that point in time.
On the second day at work, I wasn’t completely comfortable with everything happening around me. My excitement got the best of me, and as a result, I accidentally hurt myself.
To be fair, it wasn’t Isaac who should bear the blame for his lack of knowledge about Harry Potter’s spells. After all, he wasn’t expected to know every spell under the sun. In such a situation, if someone hadn’t intervened when Isaac was casting an unforgivable curse, Lucius would have had to do so instead.
It’s intriguing to contemplate what lies ahead for the enchanting Wizarding World, as the Fantastic Beasts series appears stagnant following the lackluster box office performance of its latest installments. Despite the upcoming Harry Potter TV series, fans remain curious about the potential release of a movie adaptation of The Cursed Child.
The Harry Potter series is currently available for streaming on Max. As for future films, nothing has been scheduled for the 2025 movie release or beyond; however, the franchise has grown more recently due to expansions at Universal Theme Parks.
