Originally Zwie Herzen in Drei-Vertel Takt, this delightful operetta was written directly for the screen by Robert Stolz. Nicki and Vicki, two librettists who also happen to be brothers, are presently in collaboration with composer Toni. All too aware of Toni's amorous escapades, Nicki and Vicki try to keep the existence of their pretty sister Hedi a secret. Suffering from a acute case of writers' block (he has yet to find an inspiration for his next production), Toni throws a huge party, which is boycotted by his friends and associates so that he'll keep his mind on his work. The only guest who does show up is uninvited -- and surprise, that guest is sweet little Hedi, who turns out to be inspiration enough for ten operettas. Two Hearts in 3/4 Time was a worldwide financial and critical success, with most of the credit going to cherubic supporting player Szoeke Szakall, who would go on to even greater fame in Hollywood as S. Z. "Cuddles" Sakall.
