Rhythm Is It! is a 2004 German documentary film directed by Thomas Grube and Enrique Sánchez Lansch. The film documents a project undertaken by conductor Simon Rattle and choreographer Royston Maldoom to stage a performance of Stravinsky's Le Sacre du printemps (The Rite of Spring) with a cast of 250 children recruited from Berlin's public schools. The choreographer inspired the young people from 25 countries in demanding rehearsals to work seriously and act as an ensemble, overcoming obstacles and frustration, and to find self-confidence based on body perception. A successful performance was given for 3000 spectators in the Berlin Treptow Arena in January 2003.
