Paramount Pictures’ Bob Marley biopic “Bob Marley: One Love” outperformed expectations to debut at No. 1 at the box office with a $27.7 million opening weekend, while Sony’s “Madame Web” flopped with one of the lowest debuts for a movie centered on a Marvel character.

Both films launched in theaters on Tuesday to rope in Valentine’s Day moviegoers. But on a weekend that was once expected to go to “Madame Web,” “One Love” emerged as the much-preferred option in theaters.

“One Love,” starring Kingsley Ben-Adir and produced with the involvement of the Marley estate, performed roughly on par with previous hit musical biopics like “Rocketman” and “Elvis.” Paramount is forecasting that “One Love” will gross $51 million over its first six days, including estimates for President’s Day on Monday. It added $29 million from 47 international territories.

Labor board is unconstitutional, Amazon says

Amazon is arguing in a legal filing that the 88-year-old National Labor Relations Board is unconstitutional, echoing similar arguments made this year by Elon Musk’s SpaceX and the grocery store chain Trader Joe’s in disputes about workers’ rights and organizing.

The Amazon filing came late last week in response to a case before an administrative law judge overseeing a complaint from agency prosecutors who allege the company unlawfully retaliated against workers at a New York City warehouse who voted to unionize nearly two years ago.

In its filing, Amazon denies many of the charges and asks for the complaint to be dismissed. The company’s attorneys then go further, arguing that the structure of the agency — particularly limits on the removal of administrative law judges and five board members appointed by the president — violates the separation of powers in the Constitution.
