Friday the 13th is James Wan’s lucky day.

Audiences turned out in droves to check out Insidious: Chapter 2, which opened at an impressive $20 million. Film District’s PG-13-rated thriller opened in 3,049 theaters with significant social media and pre-sale buzz working in its favor. It’s also been a great summer for modestly budgeted horror films, including The Purge and Wan’s own The Conjuring. Rose Byrne and Patrick Wilson reprise their roles as the poor parents just trying to protect their unlucky son from the demon spirits they thought they were rid off at the end of the first film. The $5 million film, boasting a $6,579 location average, should walk away with at least $40 million this weekend, even with the likelihood that teens won’t turn out in the same numbers on the significantly less exciting Saturday the 14th. Still, this is on track with The Conjuring, which also starred Wilson and opened at $41.8 million in mid-July.

The Family, Robert De Niro and Michelle Pfeiffer’s mob comedy about a family forced to relocate to a sleepy French town under the witness protection program took in about $5.4 million on Friday, with a $1,747 location average. Directed by Luc Besson, The Family opened in 3,091 theaters and is poised for a $12-$15 million weekend — a decent opening for Relativity’s $30 million movie. Glee’s Dianna Agron also stars as the feisty teenage daughter.

Meanwhile, Vin Diesel’s $38 million Riddick earned an estimated $2.2 million on Friday in 3,117 theaters, and will likely bring in around $6.6 million this weekend. The second weekend drop will be almost 70 percent for Universal’s sci-fi action pic — much steeper than the 61 percent drop for 2004’s Chronicles of Riddick.

In fourth place, We’re the Millers dropped about 24 percent from last weekend with $1.74 million, bringing its domestic total to $127.9 million. After six weeks in theaters the $37 million Jennifer Aniston and Jason Sudeikis marijuana comedy is still playing in 3,238 theaters and experiencing incredibly modest weekend to weekend drops in the 27 to 40 percent range. Finally, in fifth place, Lee Daniels’ The Butler took in $1.66 million on Friday, putting it on track for a $5.8 million weekend. The $30 million movie will cross $100 million in its fifth weekend in theaters — a first for Daniels.

1. Insidious: Chapter 2 – $20 million

2. The Family – $5.4 million

3. Riddick – $2.2 million

4. We’re the Millers – $1.74 million

5. Lee Daniels’ The Butler – $1.66 million

Despite a continued expansion, Instructions Not Included dropped out of the top five on Friday, with $1.39 million, but could pick up steam throughout the weekend to knock Lee Daniels’ The Butler or We’re the Millers out of their slots.
