Jan. 31 (UPI) -- Jason Isaacs sent Harry Potter fans into a frenzy Monday when he shared on social media a mini-reunion he was having with co-stars Tom Felton and Matthew Lewis.
"Me, @TomFelton & @Mattdavelewis marvel at them getting older as I get younger. To all the Potter fans who remind us to fight for the light," the actor wrote on Twitter alongside a photo of himself posing with Felton and Lewis.
The trio came together to visit the Wizarding World of Harry Potter at the Universal Orlando Resort.
The gathering also surprised series creator J.K. Rowling who shared the photo on Twitter alongside a heart and lightning bolt emoji.
Isaacs is known for appearing in the Harry Potter series as Lucius Malfoy with Felton playing his son Draco Malfoy and Lewis starring as Neville Longbottom.
Isaacs also shared another group photo that included Warwick Davies who portrayed Professor Flitwick and Griphook, a goblin of Gringotts Bank in the series.
"Here's the album cover. Now all we have to do is come up with the songs. Titles anyone?" the caption reads on Instagram.
Also on Instagram, a selfie with Felton was shared while inside the park. Isaacs captioned the image detailing their trip to Universal and how Harry Potter relates to the real world.
"Me and the wizarding blond bombshell reunited and wandering around Universal's #wizardingworldofharrypotter extremely cognito," the 53-year-old wrote.
"A welcome escape from the horrors of the world until we answered questions on stage and were reminded what the stories were all about: fighting fascism, embracing diversity and never giving up hope. Suddenly seemed a lot less fantastical. Still, huge love and thanks to all the Potterites who made it a glorious weekend. You're all brilliant - even the tragically unSlytherin."
