You'll feel a mix of emotions watching Riverdale's season three gag reel. The video, which was released at San Diego Comic-Con over the weekend, includes a ton of hilarious moments among the cast members, but it also includes some sweet behind-the-scenes footage of the late Luke Perry. At one point, Perry cracks a dad joke as he sits at the table with KJ Apa, who plays his son Archie on the hit CW series.
In March, Perry died at age 52 after suffering a massive stroke. Though the series dedicated all future episode of season three in his honor, the season four premiere will pay tribute to his beloved character, Fred Andrews. During Comic-Con, showrunner Robert Aguirre-Sacasa announced that Riverdale had enlisted Perry's former Beverly Hills, 90210 cast mate Shannen Doherty to help with the special episode. "They were such good friends, and when we were putting together this tribute episode, we wanted to make it as special as possible," he said. "And so we asked Shannen to do a pivotal, super-emotional role. She read the script and immediately said 'yes.' It's very impactful."
