In 1977, Roy E. Disney, the son of Disney co-founder Roy O. Disney and nephew of Walt Disney, resigned as an executive due to disagreements with his colleagues' decisions at the time. As he claimed later, "I just felt creatively the company was not going anywhere interesting. It was very stifling. " However, he retained a seat on the board of directors. His resignation from the board in 1984, which occurred in the midst of a corporate takeover battle, was the beginning of a series of developments that led to the replacement of company president and CEO Ronald William Miller (married to Walt's daughter Diane Marie Disney) by Michael Eisner and Frank Wells. Roy soon returned to the company as vice-chairman of the board of directors and head of the animation department.
