Los Angeles ? Audiences made a date with “Prom Night,” the remake of the 1980 slasher flick that took in $22.7 million to debut as the weekend’s No. 1 movie, according to studio estimates Sunday.

The movie, released by Sony’s Screen Gems banner, stars Brittany Snow as a teen terrorized by a psycho killer on prom night. It overcame the critical drubbing handed to most fright films, which have a built-in audience that often turns out in big numbers on opening weekend regardless of reviews. It may also have been helped by having prom season in full swing.

Opening in second place was 20th Century Fox’s “Street Kings,” a cop drama starring Keanu Reeves and Forest Whitaker that took in $12 million.

The new movies bumped Sony’s “21,” which fell to third place with $11 million after two weekends at No. 1. The Vegas blackjack tale raised its three-week total to $62.3 million.

The weekend’s other new wide release, Miramax’s “Smart People,” opened at No. 7 with $4.2 million. “Smart People” stars Dennis Quaid, Sarah Jessica Parker, Ellen Page and Thomas Haden Church in a comic drama about a crusty English professor and his oddball family and associates.

In limited release, Fox Searchlight’s documentary “Young Heart” took in $52,312 at four theaters over the weekend and $63,606 since opening Wednesday. The film follows a chorus of elderly singers averaging about 80 who sing punk and pop songs by the Clash, Coldplay, the Talking Heads and other modern bands. It expands to 28 more theaters Friday.
