Once again her lateness became legendary on the set, but by now the other actors and actresses were becoming used to it, as [Elliott] Reid remembered: ‘She was often late- sometimes ten minutes or so, but not extreme; her lateness was well known and it was just how she was. She was charming and everyone understood her lateness and nobody got mad. There were no problems during the making of the film because she was so sweet; she was never aggressive-she just wanted to do her best.’
Jane Russell sympathized with the nerves that caused Marilyn to be late, and made a point of trotting past her dressing room in order to walk her to the set each day. This helped with her punctuality, but not her nerves, and she would visibly shake between scenes, as George Chakiris observed on the first day of shooting the ‘Diamonds’ number: ‘Marilyn was sitting on the round sofa used during the song, and I noticed the muscles in her back quivering from nerves,’ he later recalled.
