Remember the fantastic Kevin Spacey movies of the 90's? LA Confidential, Seven and The Usual Suspects were all great movies with Spacey playing the pivotal role in each. American Beauty turned him into a Best Actor. Then came the crap. Pay It Forward, K-Pax, Shipping News. The Life of David Gale, his latest film, died at the Box Office and should be showing on an airplane near you. I know we will probably never see as good of a character as Verbal Kint, but it would be nice to see him in a good movie for a change.
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
