Butterfly on a Wheel (US: Shattere) is a drama film starring Pierce Brosnan, Maria Bello and Gerard Butler. It was released in 2007. The film’s title is an allusion to a line of Alexander Pope’s Epistle to Dr Arbuthnot: “Who breaks a butterfly upon a wheel?” The line is usually interpreted as questioning why someone would put massive effort into achieving something minor or unimportant.
