21 times real-life fathers and sons played family on-screen

Kirk Douglas, his son Michael, and his grandson Cameron all appeared in “It Runs in the Family” as three generations of the Gromberg family in 2003.

In “It Runs in the Family,” each generation of Gromberg men is dealing with their own issues — Kirk’s character, Mitchell, is struggling with health complications after a stroke; his son Michael’s character, Alex, is trying to manage marital issues and career doubts; and his son Cameron’s character, Asher, is feeling lost while away at college.

To add even more Douglas genes to the film, Michael’s mother and Kirk’s ex-wife, Diana, also appeared in the film as Mitchell’s wife, Evelyn.

Diana died in 2015, while Kirk died in 2021. After his father’s death, Michael posted a tribute on Instagram, “To the world he was a legend, an actor from the golden age of movies who lived well into his golden years, a humanitarian whose commitment to justice and the causes he believed in set a standard for all of us to aspire to.”

“But to me and my brothers Joel and Peter he was simply Dad, to Catherine, a wonderful father-in-law, to his grandchildren and great grandchild their loving grandfather, and to his wife Anne, a wonderful husband,” he continued.
