William Powell led a very interesting life. If you ever get a chance to read his biography, it would be a worthwhile read. Here are a couple highlights:
On June 26, 1931, Powell married actress
Carole Lombard. The marriage lasted just over two years. They were divorced in 1933, though they, too, remained on good terms, even starring together in the screwball comedy
My Man Godfrey three years later. Powell was devastated by her death in an airplane crash in 1942.
[4] He was engaged to marry
Jean Harlow, his co-star in
Reckless (1935), until her sudden death in 1937.
[5][6] On January 6, 1940, three weeks after they met, Powell married his third wife, actress
Diana Lewis, to whom he remained married until his death in 1984.
In 1937, Powell was diagnosed with cancer. He underwent surgery and experimental radium treatment which put the disease in full remission within two years. Given his own health and sorrow over Jean Harlow's death, Powell did not undertake any film roles for over a year during this period.
