"I was very proud of it and, you know, my dad was really proud of it and he was really excited about it," said Luke, adding "it was cool to see that and I'm glad he got to do that."
The 51-year-old Riverdale actor passed away in March this year from a stroke.
His son Jack is a professional wrestler known as Jungle Boy.
On Monday, he climbed a giant billboard for the Once Upon a Time in Hollywood premiere in LA.
"Big premiere tonight. He deserved this, and I’m very proud of it. A stud in life, and forever after. The best of the best. Love you forever," he wrote in the caption of a video he shared of his climb to the top.
Jack explained his reason for scaling the billboard to Entertainment Tonight, saying "I like climbing stuff and I saw it there. I just wanted to - it will only be there for so long and I kind of wanted to commemorate it being there forever in a way and it's kind of just my natural thing to go climb on stuff."
The 22-year-old said that while he didn't entirely relate to those mourning him around the globe, he still appreciated it.
"I think everyone gets it in their own way."
Jack also expressed that he was proud of his dad for being a good person.
'The thing that I'm most proud of about my dad, always, is that he was a really good guy,' he said.
