Ahhh, Groupon. The deal-of-the-day website where you can score discounted personal training sessions, Mexican cooking lessons and now, thanks to a partnership with Lionsgate, half-off tickets to the new Matthew McConaughey legal thriller The Lincoln Lawyer. "Groupon is one of the most dynamic young companies in the world today, and their emergence as a digital commerce pioneer made them the perfect online partner for Lionsgate and The Lincoln Lawyer," said the studio's vice chairman Michael Burns in a statement earlier today. The question remains though, would a promotional deal with Groupon have saved Mars Needs Moms? [THR]
