Houseboat

The original screenplay was written by Betsy Drake, Cary Grant's wife at the time. Grant originally wanted it to star her, but his extramarital affair with Sophia Loren complicated the project. Grant decided to have Loren replace Drake. Adding insult to injury, it was drastically rewritten to accommodate Loren by two other writers, Jack Rose and Melville Shavelson (who also directed). Bearing little resemblance to her original script, Drake received no writing credit, and the reworked script was Oscar®-nominated for Best Original Story and Screenplay.
