Wingreen's resume also includes featured roles in They Only Kill Their Masters, Airplane!and Star Trek: The Original Series. Wingreen told StarTrek.com in 2014 that even if his part in Star Wars was small, it forever changed his life.
"I've signed a lot of photos of Boba Fett," he said. "I was living a quiet, peaceful, unencumbered life until that news broke, and when the news came out in a Star Warsmagazine, for which I'd done an interview, the letters just never stopped."
Wingreen is survived by his son, Ned, two grandchildren and his sister, Harriet Wingreen and her family.
