“’That’s Luke f**king Perry,’” Brad Pitt previously said about his excitement about working with the former teen idol. “We were like kids in the candy shop because I remember going to the studios and Beverly Hills, 90210 was going on and he was that icon of coolness for us as teenagers. It was this strange burst of excitement that I had, to be able to act with him.
"Man, he was so incredibly humble and amazing and absolutely committed. He couldn’t have been a more friendly, wonderful guy to spend time with. I got to sit down and have some wonderful conversations with him. It was really special.”
“This evening as we celebrate the artistic highlights of the past year, we also pause to remember those in our community who we lost,” Spielberg said before the video that left out Perry began.
“Legends and icons, our friends and fellow artists all who inspired and touched us. They have left an indelible imprint on our industry, our imaginations and our understanding of the world. Let us remember our lives and let us remember their legacies.”
The television reboot of BH 90210 paid tribute to Perry in the premiere episode.
