Greta Garbo had her misgivings about appearing in a comedy and was particularly nervous about the drunk scene, which she considered to be highly vulgar.
Bela Lugosi received fourth billing even though he appears only near the end of the movie and only in one scene with Greta Garbo.
The tagline "Garbo laughs!" came before the screenplay was written; the film was built around that single, now legendary, catch-phrase. This was itself a reference to another legendary advertising slogan about Greta Garbo. A famous leading lady of the silent film era, she made her first talking picture, Anna Christie (1930). That film was advertised, to great success, with the line "Garbo Talks!" When she made this comedy the "Garbo Laughs!" tagline resonated with her fans.
The movie was banned in the Soviet Union and its satellite states.
Although Greta Garbo's famous hat in the film was made by her regular costumier Adrian, it was in fact based on a sketch by Garbo herself.
