Groupon Uses Matthew McConaughey Interview to do Boffo Box Office

Groupon is now a one-stop shop for movie discounts and celebrity dish. In a move that other Internet coupon bearers are bound to analyze, Groupon offered $6 tickets to The Lincoln Lawyer, plus an exclusive interview with the film's star, Matthew McConaughey. The two-day sale closed Thursday night, March 17, and the movie opened Friday, March 18.

It was Groupon's first time partnering with a movie studio (LionsGate) to sell price-slashed movie tickets. Groupon is also believed to be the first among social-media discounters to post original celebrity features in the same email with the coupons.

Groupon previously interviewed Rihanna to sell her album Loud at a bargain, but McConaughey is the first actor it has featured.
