Greta Garbo initially formed a very close relationship with Freddie Bartholomew until the 11-year-old asked her for an autograph for his uncle one day. After that their relationship was strictly professional. For the rest of his life he was dismayed at suddenly losing her friendship.
Aware that her co-star Fredric March was notorious for seducing his leading ladies, Greta Garbo reportedly wore garlic under her clothes and purposely had bad breath in order to stave off his advances.
In a separately filmed trailer sequence, Freddie Bartholomew talks to the audience and tells them about the picture.
