“Harry Potter” stars came out in droves Thursday to pay tribute to their co-star Sir Michael Gabon after his passing from pneumonia at age 82.

Actor James Phelps, who portrayed Fred Weasley in the film franchise, tweeted an emotional anecdote about how his cherished friend helped him with a “weekend gig.”

“In between set ups Michael asked what I was up to that weekend. As it happened my brother and I were reading Peter and the Wolf with the Manchester Halle orchestra,” Phelps recalled.

“‘Do you have the script with you?’ He asked, I did, ‘I’ve done that, let’s got [sic] through it and if you like I can give some notes.’ So we spent what should have been his downtime going over my weekend gig.

“It is a memory I’ve always had as one of the highlights of my HP days,” he concluded.

Jason Isaacs, who played villainous Lucius Malfoy in the series, tweeted that the “magnificent” Irish-English actor taught him what “acting could be.”

“The greatest thrill of being in the Potter films was that he knew my name and shared his fearless, filthy sense of fun with me,” he added.
