Matthew McConaughey's 2019 is not off to a great start at the box office.

"The Beach Bum," which opened in 1,100 theaters, also had the worst wide-release opening weekend of 2019, so far, for a movie opening in more than 1,000 theaters. For comparison, the anti-abortion movie "Unplanned" opened over the weekend in fifth place with $6 million from 1,059 theaters.

"The Beach Bum" stars McConaughey, Snoop Dogg, Isla Fisher, Martin Lawrence, and Zac Efron, and follows McConaughey's poet stoner character, Moondog, "a rebellious rogue who always lives life by his own rules."

This was noted indie filmmaker Korine's first wide release and he spoke with Business Insider's Jason Guerrasio about what that was like in an interview before the movie opened.

"It's exciting because I always wanted the movies to always be seen by as many people as they could," Korine said. "I never purposely wanted to limit them."
