Yet let me flap this bug with gilded wings

Yet one more way I know I'm not part of the main movie-going population: I just watched a DVD called Shattered, a thriller with Maria Bello, Pierce Brosnan and Gerard Butler. It's a joint UK/Canada film. And apparently, in the UK (and, I presume, Canada also), it's known as Butterfly on a Wheel (except that the version I got at the DVD place is clearly titled Shattered). To me, Butterfly on a Wheel is an infinitely better title, and I can't, for the life of me, imagine why anyone would give it a bland name like Shattered.
