Chris Pratt is mourning the recent deaths in his Everwood family.
In the wake of John Beasley and Treat Williams' passings, the actor, who played Bright Abbott on four seasons of the beloved WB show, penned a lengthy tribute to his late co-stars. Alongside a black-and-white photo of Beasley and Williams, Pratt wrote on Instagram June 13, "It's an incredibly sad season for the cast and crew of Everwood."
"We're still reeling from the loss of John Beasley and yesterday we lost Treat Williams as well," he continued. "Both men were exceptional actors, wonderful husbands, fathers and friends. They will be missed tremendously. I learned a great deal from working with each of them."
After sharing his condolences to Beasley and Williams' families, the 43-year-old added, "May we see you again gentlemen. God bless you. Hug your loved ones. Reach out to that person that's been on your mind. Life is fragile, precious and finite. Embrace it and one another."
Beasley, who starred as Irv Harper from 2002 to 2006 on Everwood, died on May 30 at the age of 79. According to his son Tyrone, he was in the process of undergoing tests on his liver when his health abruptly declined, passing away at a hospital in his hometown of Omaha, Neb.
Two weeks later, Williams—who played patriarch Dr. Andy Brown on the series—died following a motorcycle accident in Dorset, Vt. He was 71.
"As you can imagine, we are shocked and greatly bereaved at this time," his family said in a statement to NBC News. "Treat was full of love for his family, for his life and for his craft, and was truly at the top of his game in all of it. It is all so shocking right now, but please know that Treat was dearly and deeply loved and respected by his family and everyone who knew him."
Pratt is not the only Everwood star who took to social media to pay their respects. Amid news of Williams' death, Emily VanCamp remembered the "wonderful" moments they shared on set.
"I was always excited for the next time," she wrote in a June 13 Instagram post. "Sending all my love to your family Treat. Fly high my friend."
Meanwhile, Vivien Cardone, who played Williams' daughter Delia on the series, called the later actor her "second father."
"My heart is shattered," she shared in a post of her own. "In a strange new place, surrounded by unfamiliar people, you were the first person who made Utah and Everwood feel like home."
Williams' TV son Gregory Smith also opened up about his fondest memories of the star, telling E! News in a statement, "He made an indelible impression on me during my most formative years. I will always cherish my time with Treat and think fondly of his stories, his laugh and his passion for adventure."
Calling Williams a "wonderful man and a brilliant actor," Smith added, "I'm very grateful for the time I got to spend as part of his extended TV family."
