Alan Thick Dies

Alan Thicke Remembered as 'Old-School Pro,' 'Genuinely Nice Guy'

Former colleagues of Alan Thicke took to social media to pay tribute to the Growing Pains legend, who died of a heart attack Tuesday at the age of 69.

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.”

Fuller House‘s Candace Cameron Bure, the sister of Growing Pains actor Kirk Cameron, noted that she has known the iconic patriarch “since I was 8 years old.”

Thicke recently guest-starred in an episode of Fuller House. Read on for Twitter remembrances from EP Jeff Franklin and co-stars Bob Saget and Dave Coulier.

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.”
