Russell Crowe is like a malevolent Foghorn Leghorn in an oversized pickup truck in “Unhinged,” a thriller about a man who snaps and goes on a rampage. This was supposed to have been the movie that reopened theaters in the United States back on July 1. That clearly didn’t happen, but it’s here now, whether you want it or not. My 1 1/2-star review, at RogerEbert.com.
