Ian Falconer is very active in the world of theater design. He teamed up with artist David Hockney and together they collaborated on the costume designs for the Los Angeles Opera production of Tristan and Isolde (1987); he served as co-designer (sets and costumes) with Mr. Hockney on the Lyric Opera's production of Turandot (1992); and designed the costumes for The Royal Opera's production of Die Frau Ohne Schatten at Covent Garden. In 1996, Mr. Falconer designed the sets for The Atlantic Theater's production of The Santaland Diaries, written by David Sedaris. In January 2008, Mr. Falconer completed the set design and oversaw the installation for the operetta 'Veronique' at the Theatre du Chatelet in Paris. The sets were widely hailed for their use of classic stage sets married with complex moving film images that impressed audiences with innovative theatrical optical illusions.

For the New York City Ballet, Mr. Falconer has designed scenery and costumes for Scènes de Ballet (1999), and Variations Sérieuses (2001), both choreographed by Christopher Wheeldon. In 1999, he designed scenery and costumes for Boston Ballet's production of Firebird, also choreographed by Mr. Wheeldon. In 2003, Falconer designed sets and costumes for Stravinsky's Jeu de Cartes, choreographed by Peter Martins.
