'Big Daddy' actually lived a long time
First of all I was surprised that Burl Ives was only about 48 when he played a 65 year old Big Daddy but then I was more surprised that he died almost 40 years after this movie was made at the ripe age of 85. Being overweight like that made me assume that he died a long time ago but he surprisingly reached a pretty old age, dying at an older age than Liz Taylor and Paul Newman.
Ironically Jack Carson, who played his older son Gooper in the movie was only one year younger than Burl Ives and actually died of stomach and liver cancer of few years later.
