Theater St. Gallen, Switzerland. Fidelio (originally titled "Leonore, oder Der Triumph der ehelichen Liebe," which translates to "Leonore, or the Triumph of Marital Love"), Op. 72, is Ludwig van Beethoven's only opera. This 2018 opera film from the Swiss Theater St. Gallen is based on Jan Schmidt-Garre's highly acclaimed stage production of Beethoven's Fidelio. Otto Tausk conducts the Sinfonieorchester and choir of St. Gallen, as well as many wonderful soloists in a beautifully designed set by Nikolaus Webern. The producers carefully filmed and edited several performances, and by using additional footage of starring soloist Jacquelyn Wagner as Leonore, the captivating stage production is enhanced and transformed into a unique cinematic experience.
