A 70-year love story
William and Bonnie celebrated their 70th wedding anniversary in 2021, marking one of Hollywood’s longest-lasting marriages.
Speaking to Forbes, Daniels said: "I think our relationship is based on mutual respect, and I think she is smarter than me, better actor than me, and so I just hang on, you know, and try to get along."
Bonnie, meanwhile, praised his humour and added he is "a great father".
In 1961, she gave birth to a son, who tragically died 24 hours later.
They went on to adopted two sons, Michael and Robert.
William and Bonnie have four grandchildren - two each through Michael and Robert.
