A heartfelt tale about a dolphin and the humans who cared for it proved no match for Idris Elba at the box office Friday—even if he’s playing a psychotic escaped con out to terrorize Taraji P. Henson. Of course, No Good Deed and Dolphin Tale 2 aren’t even remotely in competition for the same audience. But in the box office world, for once, adults seem to be forking out more money for their own viewing pleasure.

No Good Deed is on track to beat expectations by at least $7 million. The tense, PG-13 rated thriller from sometimes Luther director Sam Miller took in an estimated $8.8 million Friday from 2,175 locations. It could net out in the $24-$25 million range once the weekend closes out, which would be a terrific result for a pic that cost a reported $13 million to produce. Audiences gave the film a B+ Cinema Score, which isn’t terribly promising for its word-of-mouth potential. Critics have been less kind—the pic currently has a 10 percent rating on Rotten Tomatoes. Still, audience thirst for a fun thriller is evident.

Meanwhile, the family flick Dolphin Tale 2 may actually fall short of forecasts. The sequel took in an estimated $4.27 million, from 3,656 locations Friday, and though things will probably pick up over the weekend, it looks poised to miss the $19-$20 million expectation—despite positive reviews (72 percent on Rotten Tomatoes) and audience reactions (Cinema Score: A). Still, this movie, which cost a reported $36 million to produce, could have staying power. The original opened in 2011 to $19.2 million and racked up $72.3 million domestically across its run.

The weekend’s other new opener The Drop, a crime drama starring Tom Hardy and James Gandolfini (in his final performance), opened in only 809 theaters and managed to snag a spot on Friday’s top five with an estimated $1.46 million. The R-rated Michael Roskam pic (penned by Mystic River author Dennis Lehane) is getting some terrific reviews (87 percent on Rotten Tomatoes) and could be on its way to a $5 million weekend.

Here’s the top five:

1. No Good Deed $8.87 million

2. Dolphin Tale 2 $4.27 million

3. Guardians of the Galaxy$2.09 million ($299.98 million domestic total)

4. The Drop $1.46 million

5. Let’s Be Cops $1.27 million ($69.9 million domestic total)

In limited release, The Weinstein Company’s The Disappearance of Eleanor Rigby: Them, starring James McAvoy and Jessica Chastain is off to a nice start with an estimated $21K from 4 locations. At press time, Friday estimates were not available for the Bill Hader, Kristen Wiig Sundance drama The Skeleton Twins, which opened in 15 locations.
