Gretl Theimer was an Austrian actress and singer whose vibrant performances captivated audiences during the golden age of European cinema. She first garnered attention with her role in the musical film *Zwei Herzen im Dreivierteltakt* (1930), one of the earliest sound films that launched her into stardom. The catchy waltz from the film, performed alongside Walter Janssen, became a chart-topping hit and solidified her status as a beloved entertainer. Collectors of physical media particularly treasure Theimer’s work in *Immortal Waltz* (1939), a quintessential example of Wiener Film that showcases her charm and talent. Her ability to embody the spirited, romantic heroines of the era makes her performances highly sought after. Although her film career waned in the late 1930s, Theimer’s influence on musical cinema remains significant, leaving collectors eager to preserve her legacy through vintage VHS, DVD, and Blu-ray releases.
