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”:
I spent Monday through Friday for seven important years with Alan Thicke as my "TV dad." I'm shocked and truly heartbroken today at the news of his death. Alan was a generous, kind and loving man. I am so blessed to have grown up with him. Chelsea and I send our love and prayers to his family tonight. We will cherish the memories… "sharing the laughter and love."
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

Thicke also appeared in the series premiere of NBC’s This Is Us, playing himself in a scene opposite Justin Hartley’s Kevin.
“I was so saddened to hear about the passing of Alan Thicke,” creator Dan Fogelman told EW.com in a statement. “It feels like just yesterday he joined us on the pilot of This Is Us — he was an absolute joy to work with and hang out with, both on and off camera. I know I speak for the entire This Is Us family as we send deepest condolences to his family, friends, and loved ones.”
