This film was a "smell-o-drama" produced for the 1940 New York World's Fair. The projectionist ran a control board to release 32 different odors into the theater, including tar, hay, roses, peaches, and coconut, to complement the action onscreen.
Kurt Früh started this movie but producer Conrad Arthur Schlaepfer, dissatisfied with his work, replaced him by a team composed of Valerien Schmidely and Rudolf Eger.
Directly after its premiere at the 1940 New York World's Fair, the movie and its special "technology" were seized by the police under the pretext that a similar system was already licensed in the United States. The Swiss promoters tried to recuperate their material, even going to court, but it proved to be all in vain. They lost their investment, "Mein Traum" was never heard of again, and "smell-o-rama" didn't become the new movie-going sensation - nor this time nor ever.
