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.
