Hjertetyven (Thief of Hearts) is a Danish short silent comedy film from 1919 directed by Lau Lauritzen Sr. The screenplay was written by Poul Gregaard. The Norwegian actress Erna Schøyen plays the leading female role as Elva Marja.
The dancer Elva Marja has a very faithful and enthusiastic admirer in Henry Corner, who is known for his wealth and eccentricity. Immediately after her performance, he writes in a letter that he has been following her from city to city for three months and hopes that she must have realized that she can no longer avoid him. Corner concludes that he will wait for Elva Marja in the vestibule. He asks a theater employee to give her the letter. Elva Marja is sitting in her changing room, surrounded by several men. She reads the letter to them, and they all laugh. Elva Marja asks the theater staff to tell "the conceited gentleman" that he should not waste his time waiting for answers. Corner is still waiting for her in the vestibule as announced. When Elva Marja passes him with her male companion, she makes a cutting remark.
