It doesn't get any better than this: closing out the year with the release of "The Mule", directed by and starring Clint Eastwood, who made his last acting appearance in "Trouble with the Curve" in 2012. In "The Mule", Eastwood, who is going on 90 years old, plays a man with a troubled past who gets caught up in the drug-smuggling trade. If the film plays as well as the trailer, it may prove to be a real gem.
