Another relatively slow weekend at the box office, as not a single new release could crack $10 million.

In at number 1 is Lee Daniels' The Butler with $17 million. Whether it’s the strong word of mouth, Oscar potential, or some combination of the two, this film dominated all new releases for the second weekend in a row and has grossed $52 million in the process.

Holding steady in the number 2 spot is We're the Millers with $13.5 million, which brings its total up to $91 million after three weeks. Horror might be the genre getting all of the attention this year, but comedies are also doing surprisingly well and this film is just one of many examples.

The Mortal Instruments: City of Bones (read our review) comes in at number 3 this weekend with $9.3 million. The film actually opened this past Wednesday and has grossed $14 million over its first five days.

While hopes were high for The Mortal Instruments, which is based on the YA series by Cassandra Clare, this first entry failed to make any serious dent at the box office, putting potential sequel talk into flux. Prior to release, Screen Gems seemed confident in the series' franchise potential, even courting Sigourney Weaver for a role in the sequel, but that will be a tough sell now.

In at number 4 is The World's End (read our review) with $8.9 million. The final entry in Edgar Wright's "Three Flavors Cornetto Trilogy" was on track for around a $13 million opening (which would have been his highest yet) early on in the weekend, but it dropped off by Sunday.

At the same time, $8 million is certainly not a bad opening for The World's End, as it only opened on 1,549 screens and tallied the best per-screen average ($5,773) in the top 10. The film is also well on its way to outgrossing Wright's other two "Cornetto" films, Shaun of the Dead ($13 million domestic) and Hot Fuzz ($23 million domestic). It's worth mentioning that The World's End opened in Europe this past July and has accrued $24 million worldwide.

Disney's animated feature Planes rounds out the top 5 with $8.5 million. The film has now surpassed its $50 million budget with $59 million domestic.

The number 6 film this weekend is Elysium with $7.1 million. Although the film has banked a solid $69 million, it won't make back its $115 million budget.

The horror film You're Next (read our review) is the number 7 film this weekend with $7.05 million. Though the horror genre has been doing very well this year and buzz for this film was very strong, You're Next simply couldn't hit similar numbers to The Purge or The Conjuring.

With that being said, You're Next was made for a very modest budget, which suggests it will make its money back. And, for a film that was hard to market without a bankable star, and without exposing how unique it is, LionsGate was likely in a tough spot.

In at number 8 is Percy Jackson: Sea of Monsters with $5.2 million. The fantastical sequel has only grossed $48 million over 3 weeks, which is well below its $90 million budget.

Woody Allen's latest film, Blue Jasmine, comes in at number 9 with $4.3 million, up 87% as it increased its theater count by about 1,000 screens. Thus far the film has grossed a very solid $14 million.

Kick-Ass 2 falls to the number 10 spot this weekend with $4.27 million. The sequel is well behind the first Kick-Ass ($34 million after two weeks), which puts talk of a third film into question.
