Many are mourning the loss of the legendary Ivan Reitman.

He passed on Saturday, in his sleep, at the age of 75.

He leaves behind his wife, Geneviève Robert, who he married in 1976.

He had three children: Jason, Catherine, and Caroline.

He also had a granddaughter named Josephine.

Reitman is best known for directing the first two films in the “Ghostbusters” franchise.

He served as producer for 2021’s “Ghostbuster: Afterlife.”

His son, Jason Reitman, served as the film’s director.

Sony CEO Tom Rothman called him “a great talent and an even finer man.”
