Joanna Kerns, who played Thicke’s wife Maggie Seaver for seven seasons on Growing Pains, called Thicke “one of the smartest and funniest men I have ever known” in a tweet to actor Daniel Franzese:
Kirk Cameron, who played eldest son Mike Seaver on Growing Pains, said he would always “cherish the memories” of his TV dad, a “generous, kind and loving man”:
Leonardo DiCaprio, who got his start on Growing Pains, released the following statement on Facebook: “Alan was a devoted father, husband, friend and role model. He knew how to harness the power of the entertainment industry to be a positive influence in so many lives – including mine. I will be forever grateful for the opportunity I had to work with Alan early in my career. He had tremendous class, a huge heart, and he taught me and so many others the valuable lessons about humility and gratitude. I’ve seen him a number of times over the years and when Alan Thicke walked in the room, quite frankly, no one was cooler. I miss him already. My thoughts and prayers are with the entire Thicke family during this difficult time.”
Thicke’s son, singer Robin Thicke, called his father “the best friend I ever had”:
Carter Bays, co-creator of How I Met Your Mother, in which Thicke recurred as himself, called the actor “one of the greats,” adding that he was “an old-school pro and a genuinely nice guy.”
Alan Thicke was one of the greats. An old-school pro and a genuinely nice guy. Prayers for his family tonight. RIP. https://t.co/RpvLg5cOy0
