It's safe to say the world was shocked when former "Beverly Hills 90210" heartthrob Luke Perry died last year after suffering a massive stroke at the age of 52. But perhaps none were more stunned than his co-star, KJ Apa, who plays Archie Andrews on the series "Riverdale." Perry played Archie's father on the show and according to Apa, was an inspiration to the younger actor. "I had never gone through anything like that before," he told Mr. Porter's The Journal in the Fashion section. "I've never lost anyone close to me, so it was a really hard time. It’s still hard."
