Katharine Hepburn requested Clark to play
her ex-husband CK Dexter Haven in The Philadelphia Story (1940). They sent
Clark the script. He deemed it "too wordy" and said "other than pushing the
dame down, I don't have anything to do." So the part went to Cary Grant.
Carole Lombard was interested in the screenplay for Woman of the Year (1942). She thought it would be a perfect chance for her and Clark to
re-team on screen. She was very disappointed to learn that Katharine Hepburn
had snatched up the rights to it and it was going forward with her and
Spencer Tracy.
Clark very much wanted to star as Bick Benedict in Giant (1956) but director George Stevens nixed the idea, citing him as being too
old. The role instead went to Rock Hudson.
MGM wanted him to star in Home
from the Hill (1960) but Clark refused, still bitter about the lack of
appreciation MGM had showed him when his contract had not been renewed. The
role went to Robert Mitchum.
