Marc Gilpin, the actor best known for his portrayal as Sean Brody in Steven Spielberg's "Jaws 2," has died, according to his sister, actress Peri Gilpin.
Marc Gilpin had been battling cancer and passed away in Dallas on July 29. He was 56. Peri Gilpin remembered her brother's strong relationship with his wife Kaki in a touching tribute penned on Instagram.
"Kaki and Marc took care of each other with kindness, strength, dignity and invaluable humor," she wrote. "When Marc became ill, Kaki and their boys surrounded Marc with love, hugs, and round the clock support and care."
"I just want to say how much I admire Kaki as a wife, mom, first grade teacher, sister and sister-in-law and undaunted caregiver. You are an amazing person Kaki and its so easy to see how much he has always loved you and always will."
Gilpin originally announced her brother's death to The Hollywood Reporter.
