It was a very slow Labor Day weekend at the box office, with most films failing to break $10 million yet again.

Coming in at number 1 this weekend is the concert film One Direction: This Is Us with $17 million. It wasn't going to take much to crack the top spot during a slow weekend like this, so it's no surprise that fans were able to propel This Is Us to number 1.

As far as concert films go, This Is Us' opening weekend tally is a bit on the low end, behind films featuring Hannah Montana (a.k.a. Miley Cyrus), the Jonas Brothers, and Michael Jackson. Fun fact: This Is Us is documentary filmmaker Morgan Spurlock's best opening weekend tally (by a very large margin), and it is also his highest grossing film after only three days.

The number 2 film this weekend is Lee Daniels' The Butler with $14.7 million. The historical drama continues to feed off strong word of mouth and is now up to $70 million after three weeks.

We're the Millers comes in at number 3 with $12.6 million, dropping only 3% from last weekend. The Jennifer Aniston and Jason Sudeikis comedy's domestic total is now up to an incredible $109 million.

In at number 4 is Planes with $7.7 million, which brings its total up to $70 million. Much like We're the Millers, Planes retained almost all of its audience, dropping only 9% from last weekend.

Rounding out the top 5 (and coming out of nowhere) is Instructions Not Included with $7.5 million on only 347 screens. Instructions was distributed under Lionsgate's relatively new Pantelion label, which focuses on features for Latin American audiences. Pantelion's previous releases, Girl in Progress and No Eres Tu, Soy Yo, made less than $2 million during their entire theatrical runs, so it's safe to say Instructions Not Included is a big success for them.

The number 6 film this weekend is Elysium with $6.3 million, which brings its domestic total up to a solid $78 million. Unfortunately, the sci-fi blockbuster cost $115 million to make, and is well below the $115 million domestic tally set by Neill Blomkamp's first film, District 9.

Coming in at number 7 is The Mortal Instruments: City of Bones with $5.2 million. Now at $22 million domestic, this first film in a planned franchise might be the only one made.

The World's End falls to number 8 this weekend with $4.7 million. Although Edgar Wright's latest, now at $16 million domestic and $32 million worldwide, has passed Shaun of the Dead's box office tally, it will need some help to catch Hot Fuzz ($23 million) and Scott Pilgrim ($31 million).

Sept 1 Box Office - Getaway

The Ethan Hawke thriller Getaway (read our review) comes in at a very disappointing number 9 with $4.5 million. Despite a heavy marketing push, the film simply could not make a splash during this slow holiday weekend. Not even pop star Selena Gomez, who gets roped into Hawke's race against time to save his wife, could boost Getaway's profile. The film will be lucky enough to make back its $18 million budget, let alone turn a profit.

In at number 10 is Percy Jackson: Sea of Monsters with $4.4 million. The film is now up to $45 million total, barely half of its $90 million budget.

Outside the top 10: the political thriller Closed Circuit (read our review) opened at number 15 with $2.5 million. Like Getaway, Closed Circuit received a strong marketing push, but couldn't turn that into worthwhile box office dollars.
