Arthur Miller revised the script so that more emphasis was given to his wife, Marilyn Monroe. Gregory Peck, originally cast opposite Monroe, left the project, unhappy about the way his role had been diminished. He said the script was "now about as funny as pushing grandma down the stairs in a wheelchair." In addition he did not want to work with Monroe after hearing about her reputation for being late every day. Rock Hudson was considered an ideal replacement based on his ability to play comedy, but Universal would not release him. That pleased Monroe, who wanted Montand for the part.
