[7] Miller published a series of eight pieces for the Saturday Evening Post in 1956 titled "My Dad, Walt Disney", co-written with Pete Martin.

[9] After her husband was removed from his executive position at Walt Disney Productions in 1984, Miller began to limit her involvement with the company.

[10] In an interview with Miller in 2005, she recalled that she and Ron lived a typical life, as both parents were very protective, caring and loving.

[11] After her husband joined the Disney company, Miller traveled to Napa Valley with her mother, Lillian, to visit several wineries.

[12] They expanded the winery to only using estate-grown grapes, and Diane helped create a home and a family-like atmosphere rather than just a business.

Miller was instrumental in pushing ahead with the Walt Disney Concert Hall in downtown Los Angeles.

By 1996, the project was almost dead, but Miller persuaded Gehry to move forward with it, despite problems with poor management and disagreements over the design, and Los Angeles County officials' attempts to cancel it.

[14] In 2015, the inaugural Diane Disney Miller Lifetime Achievement Award was created to honor the museum's founder, to recognize those who have made an outstanding impact in the field of arts, education, community involvement, or technological advancements.

[15] Miller died on November 19, 2013, at age 79 (less than one month short of her 80th birthday) from medical complications that developed after a fall in September the same year.
