Question: Which character did British actor Christian Bale play in the 1999 film A Midsummer Night's Dream?
Context: A Midsummer Night's Dream is a two-act ballet choreographed by George Balanchine to Felix Mendelssohn's music to Shakespeare's play of the same name.  In addition to the incidental music, Balanchine incorporated other Mendelssohn works into the ballet, including the Overtures to "Athalie", "Son and Stranger", and "The Fair Melusine", the "String Symphony No. 9 in C minor" and "The First Walpurgis Night".  "A Midsummer Night's Dream", Balanchine's first completely original full-length ballet, premiered at New York City Ballet on 17 January 1962, with Edward Villella in the role of Oberon, Melissa Hayden in the role of Titania, and Arthur Mitchell in the role of Puck.  The ballet employs a large children's corps de ballet.  Act I tells Shakespeare's familiar story of lovers and fairies while Act II presents a strictly classical dance wedding celebration.  The ballet dispenses with Shakespeare's play-within-a-play finale.  "A Midsummer Night's Dream" opened The New York City Ballet's first season at the New York State Theater in April, 1964. "R U Professional" is a 2009 satirical song by the American indie rock band The Mae Shi, inspired by a July 2008 outburst by actor Christian Bale on the set of "Terminator Salvation".  Bale was filming with actress Bryce Dallas Howard when he berated director of photography, Shane Hurlbut, for walking into his line of sight.  An audio recording of the incident appeared on website TMZ on February 2, 2009.  The Mae Shi composed and recorded the song later in the same day, and released it the next day.  The group stated that the piece was created to honor Bale.  The song parodies Bale by sampling his voice from the 2008 diatribe.  The chorus incorporates Bale's use of the word "professional" from his flare-up.  The lyrics reference several films the actor starred in, including "Newsies", "Swing Kids", "American Psycho", and "The Dark Knight".
