VIDEO EXCLUSIVE: Jason Isaacs Reveals His Favorite ‘Harry Potter’ Moment With Tom Felton

Jason Isaacs, known for playing Lucius Malfoy in the Harry Potter films, revealed his favorite memory from working on the series in a new uInterview.

“They made eight films, and I was in, can’t remember actually, five or six of them over the course of 10 years. It’s a bit like saying, ‘Do you have a favorite memory of the 80s or the 90s.'” he joked to uInterview’s Erik Meers. “I mean, first of all most of my memories are too X-rated to share with the public, nothing to do with the making of the film.”

“But I guess if I had one thing: my relationship with Tom [Felton], who I’m still friendly with, who played my son. To know someone, like I know my children, from being this big, to being this big, to being this big, to being a man, and still be friendly and you know love him is great,” he continued.

“But I think if I had to freeze-frame anything, it would be the time that we shot the great big battle of Hogwarts in the courtyard at the end,” the actor said. “And it wasn’t the filming of it, it was the fact that we couldn’t film it. It was pouring with rain. And in my memory it was weeks, maybe it wasn’t, but if we were shooting the film in America, everybody would have gone to their trailers or maybe not even come to work. But, we’re British actors, we come from the theatre, and everybody huddled in a tent by these gas heaters drinking stale tea that the spoon would stand up in, huddled around the fire at the gas heater listening to Julie Walters tell stories about her pig farm, and Jim Broadbent tell stories and Emma [Watson] tell stories, and just, I was sitting with the people who were maybe the greatest actors in the English language alive today.”

He ended the anecdote saying, “I couldn’t believe I had a front row seat to that, and I prayed for the rain to continue. And that’s one of my favorite memories.”
