Which of Matthew McConaughey‘s films would you guess pays him the highest residual checks of any film he’s done?

Interstellar? The Wolf of Wall Street? Magic Mike?

You already know the real answer — it’s in the headline, after all — but it’s still surprising that the answer is 2003’s How to Lose a Guy in 10 Days.

“How to Lose a Guy in 10 Days is the gift that keeps on giving,” McConaughey told the Happy Sad Confused podcast. “I think it’s probably my favorite rom-com I’ve done. And a lot of people love that rom-com. It still pays the best ‘mailbox money’ of any film I’ve ever done. By far. … When [home video] used to be just DVDs or cable [instead of streaming or VOD], every March I’d get a big check because of Valentine’s Day.”

In the Donald Petrie film, “a high-powered ad executive (McConaughey) bets he can make any woman fall in love with him in ten days; he unknowingly picks a magazine writer (Kate Hudson) who is executing her own covert assignment to drive a man away in the exact same timeframe.”
