Shirley MacLaine is pretty much awesome and Nicholas Cage is good when he has to play an actual character and not a “star,” so it was a foregone conclusion that “Guarding Tess” (1994) would be a decent movie. MacLaine is the president’s cantankerous widow and Cage is the stoic in charge of her Secret Service detail. It’s pretty much “Driving Miss Daisy” with no black people. (That’s a description, not a value judgment.) Dealing with mortality. Dealing with the fact that your calling doesn’t match your ambition. Plus some wacky hijinks. And the president is a George W. Bush premonition.
