Jason Isaacs supported movie son Tom Felton in ‘Harry Potter’ Broadway debut

It’s a “Harry Potter” reunion.

Jason Isaacs, who played Lucius Malfoy in the blockbuster film franchise based on J.K. Rowling’s books, celebrated his former costar Tom Felton’s Broadway debut in a post to social media Nov. 16. Felton, 38, played Draco Malfoy, Isaacs’ character’s son in the “Harry Potter” adaptations.

“I came. I saw. He conquered,” Isaacs, 62, wrote in the post alongside a series of photos of him and Felton. Felton is currently reviving his role as Malfoy in a Broadway production of “Harry Potter and The Cursed Child.” The show, playing at The Lyric Theatre in New York City is running for a limited six-month window.

“You had your own giant boots to fill, son, and you burst them at the seams,” Isaacs wrote, alongside photos of Felton in costume, and the two actors embracing. “So brave. So proud. So glad to be there.”

Isaacs isn’t the only fan of Felton’s performance. Earlier this month, footage shared on social media revealed the star earned a thunderous reception when he hit the stage for his first show.

Before the actor could even utter his first line, the mere sight of the actor made viewers erupt into cheers. Ever the showman, Felton calmly delivered his dialogue once the applause settled down.
