“Champagne Problems” (*** out of four) was a sparkling romantic comedy about a female business executive (Minka Kelly) who travels to France to see about acquiring a worldwide champagne company but instead falls in love with the champagne founder’s son (Tom Woniczka). No Dom Perignon or Kristal but good-natured performances and chemistry from the two leads and some occasional laughs make this a smooth and sweet brew. Highlight: a German character’s interpretation of “Die Hard” and how Hans Gruber was a misunderstood hero.
