The first time I met Luke Perry we talked about what kind of movie we wanted "Buffy" to be. I asked if he'd ever seen "Near Dark" and he gave me a look of HOW DARE YOU SIR and I knew we'd get along. Funny, committed, and always gracious.

Dearest Luke, I will forever bask in the loving memories we've shared over the last thirty years. May your journey forward be enriched by the magnificent souls who have passed before you, just like you have done here, for those you leave behind.

This is so so sad. Luke Perry has died at the age of 52 after suffering a massive stroke. He was surrounded by his children Jack and Sophie, fiancé Wendy, his ex-wife, and his family and friends. Thinking of them all today.???? #LukePerry

Crushed. Luke Perry was truly a great guy. Warm, kind, generous and hard working. We met very young, I witnessed the grace with which he became a pop icon & parent. He's been an awesome example of how to stay decent in a swirl of crazy.
