Charade Determine the protagonist

Audrey Hepburn read the movie script of "Mystery in Mystery" and expressed interest in participating in the show, but hoped that Cary Grant would be the leading actor. After reading the script sent by Stanley Donen, Cary Grant also found it very interesting. He also said that the prerequisite for the role is that Audrey Hepburn will act as the heroine. However, he had a contract to fulfill at the time, so he could not participate for the time being. The film company subsequently suggested to find Paul Newman as the leading actor, but failed due to compensation issues. Later, the film company suggested to look for Henry Warren Beaty and Natalia Nikolaevna Zakharenko instead. Unexpectedly, after the two agreed to act, the film company actually said that it had no budget to shoot this movie. Stanley Donen then switched to the film company he was cooperating with. At this time, Cary Grant told Stanley Donen that he didn’t like the movie he planned to make, and he could take over the filming of "Mystery in Mystery." .
