This is very sweet. Luke Perry's son, Jack wanted to pay tribute to his late dad who is starring in the new movie, Once Upon a Time in Hollywood. Luke was very proud of the role in the movie, and now there is a billboard promoting him in Hollywood. On Sunday, Jack, Luke's son (who is also a professional wrestler) climbed up on the billboard to honor his dad. Check out the video and the sweet words that Jack wrote about his dad. I'm looking forward to seeing that movie. It was Luke's final performance on film.
