Matthew McConaughey says the movie that continues to earn him the biggest residual checks isn't his Oscar-winning Dallas Buyers Club or the sci-fi hit Interstellar—it's the 2003 romantic comedy How to Lose a Guy in 10 Days. In an interview with Entertainment Weekly, McConaughey called the film the "gift that keeps on giving," saying it generates the best "mailbox money" of any project he's ever done—and "by far." Before the streaming era, he said he'd reliably receive a large residual check every March thanks to viewers revisiting the movie around Valentine's Day. McConaughey also called How to Lose a Guy in 10 Days his favorite romantic comedy, saying it has become a lasting cornerstone of the genre. He credited the film's success in part to his chemistry with co-star Kate Hudson, recalling that they clicked almost instantly during the casting process through playful banter and an easy rapport.
