According to contemporary articles in the Los Angeles Times and The Hollywood Reporter, Van Johnson was originally set to star as Matthew Kingston. A MGM press release even reported filming had begun with Johnson in the cast.
After their evening of gambling, Matthew goes to Allison's hotel room and she invites him for coffee. Just as he accepts and begins to sit down, the far shot shows her putting her empty coffee cup at his place. The next shot, which is a close shot from her right, shows her again putting the cup in front of him.
