Ivan — the Hollywood producer and director behind popular movies such as Animal House, Ghostbusters and Stripes — died peacefully in his sleep at his home in Montecito, California, on Saturday, his family confirmed to the Associated Press on Monday.

"Our family is grieving the unexpected loss of a husband, father and grandfather who taught us to always seek the magic in life," said his children Jason, Catherine and Caroline Reitman in a joint statement.

"While we mourn privately, we hope those who knew him through his films will remember him always," they added.

Among those who posted tributes to Ivan following his death were Paul Feig, who directed 2016's Ghostbusters: Answer the Call, and Ernie Hudson, who starred as Winston in Ghostbusters (1984), its 1989 sequel and Afterlife.

"I am deeply saddened by the loss of Ivan Reitman," Hudson, 76, tweeted Monday. "Truly a great man and filmmaker who I had honor and privilege of knowing and working with. Deepest condolences to Jason and the entire family. May he RIP."

Arnold Schwarzenegger — who starred in several of Ivan's films, including Kindergarten Cop, Twins and Junior — shared a trio of snapshots with the director, along with a lengthy statement in which he referred to the late Ivan as "bigger than life" and "comedy royalty."

"I can't believe I won't work with him again or hang out with him again or just schmooze about life again. But I also know that Ivan isn't gone, he's still with us. He's here, in so many pages of my story," said Schwarzenegger, 74, in part. "And if you were ever lucky enough to meet him, or just experienced his work, he's part of your story, too. Thanks for everything, Ivan."
