Prom Night took the box office crown this weekend, scaring up an estimated $22.7 million.

The PG-13 horror movie capitalized on a slow month (the calm before the summer storm) and the best April horror opening day in history (it made $9.6 million on Friday). The movie is a remake of the Jamie Lee Curtis version in 1980 and just for comparison it made about $14 million during its entire theatrical run.

Around this time every year a horror movie slips into the top spot, incredibly critic proof. This one had about 14% positive reviews and easily bested the competition. However, Prom Night still outpaced modest expectations from analysts and studio experts alike. It cost about $20 million to make.

In far second place was Keanu Reeves action/cop drama Street Kings with $12 million.

The first place finisher the last two weekends, 21, dropped to a still respectable third place with $11 million. The blackjack movie has almost doubled its budget with $63 million in total so far.

The only other new opener was dark comedy Smart People, starring Ellen Page among others. Juno’s return the box office top ten wasn’t as glorious as she had hoped (it only made $4.2 million), but was still in line with expectations.

Leatherheads continues to struggle, adding only $6.2 million to a disappointing $21.9 million total. It cost at least $58 million to make.

Ticket sales were down 13% from this weekend last year, the eighth declining week out of the last nine. Final numbers are due out Monday afternoon.
