The thriller No Good Deed, starring Idris Elba, earned $24.5 million in its opening weekend, according to Entertainment Weekly.

The film also stars Taraji P. Henson as a mother who is terrorized by Elba’s character. Sam Miller directed the flick, while Aimée Lagos wrote the script.

“We were always very high on the film and felt that it would really work,” said Rory Bruer, Sony’s president of worldwide distribution, in an interview with Entertainment Weekly. “When you put all the elements together — great casting with Idris and Taraji, and this very, very suspenseful, taut thriller that Sam Miller delivered — it worked really well.”

“We really felt we were going to win. We felt we were in the zone and had a film that people were really going to like,” added Bruer.

The film was shown at 2,175 cinemas across the country to a female-majority audience. Sixty percent of audience members were reportedly female, while 41 percent of No Good Deed movie-goers were younger than 30.

Dolphin Tale 2 nabbed the second spot, earning $16.5 million at 3,656 locations. It was the movie’s opening weekend, and it proved to be less popular than its original, which grossed more than $19 million when it debuted.

Guardians of the Galaxy continues to generate big money for Marvel. The superhero film ranked third at the box office and earned just more than $8 million, bringing its domestic total to $305.9 million. Global sales for Guardians of the Galaxy has topped $600 million — and it has yet to open in China.

Megan Fox’s Teenage Mutant Ninja Turtles remake and the buddy-cop comedy Let’s Be Cops round out the fourth and fifth box office spots, respectively.
