Anecdotes

Vivian Vance (Leah) and Philip Ober (Gregory) were married. This is the only film they both appear in, but they have no scenes together.

This film uses a real, albeit early, electroencephalograph (EEG) machine, with Ellen sitting in a Faraday cage to prevent interference from external electromagnetic radiation. This was used because early EEG machines were not as sensitive or discriminatory as later, more modern devices would become.

José Ferrer, who has a cameo in the movie, and director Mel Ferrer are not related.

This was the first film Vivian Vance appeared in since Take a Chance (1933).

The exterior shot of Fairview City Hall is the City Hall of Santa Monica, California.
