John Cusack plays a fiendish sniper in Magnet Releasing’s Grand Piano (Tunes/On Demand on 1.30.14, in theaters 3.7.14), threatening concert pianist Elijah Wood with death if he plays “one wrong note.” It’s a good idea for a thriller because the metaphor applies to all public-arena performing in the 21st Century. One wrong note and you are dead. I hang my ass out on Hollywood Elsewhere 24/7, and if I write anything that rubs anyone the wrong way even a little bit, I get shot, zinged and slapped around by a lurking army of snarkers, haters, p.c. brownshirts, etc. So don’t tell me.
