Variety is a 1925 German silent drama film directed by Ewald Andre Dupont based on the 1912 novel The Oath of Stephan Huller by Felix Hollaender.
The trapeze scenes are set in the Berlin Wintergarten theatre. The camera swings from long shot to close-up, like the acrobats.
The story was loosely remade by Dupont as the 1931 German sound film Salto Mortale. From Wikipedia
