The R-rated comedy reigned supreme at the box office this weekend, proving that a restrictive rating can still reap success.

The number 1 film this weekend is Neighbors (read our review) with $51 million, which is one of the biggest debuts for an R-rated comedy. The Seth Rogen and Zac Efron warring neighbor comedy far exceeded expectations and has set the tone for the genre heading into the rest of the summer. Not to mention, the film is now Seth Rogen’s biggest opening weekend ever for a live action film.

Obviously, with A Million Ways to Die in the West right around the corner, the film will have to do a lot of its work quickly, but that should be no problem considering it seems to be winning over most audiences. But even if business dies off sooner rather than later, that’s no matter; the film already made back its budget…on Friday.

Coming in at number 2 is The Amazing Spider-Man 2 with $37.2 million. It appears the tepid critical and fan response hurt ASM 2‘s chances at a repeat, and even called into question the movie’s legs, despite it having grossed $147 million so far.

After a strong debut in its first weekend, The Amazing Spider-Man 2 dropped a substantial 59%, which isn’t unheard of for a movie of this scale, but is never a good sign. That said, the sequel is still doing excellent business worldwide, grossing $550 million so far.

The Other Woman held strong in the number 3 spot with $9.2 million. It seemed all but a given that the film would stay strong over the Mother’s Day weekend and that proved to be true. The Other Woman has grossed $61 million after 3 weeks.

In at number 4 is Heaven is for Real with $7 million. Yet again, this religious-themed film hangs on to its spot in the top 5, dropping only 30% from last weekend. All told, Heaven is for Real has grossed $75 million.

Rounding out the top 5 is Captain America: The Winter Soldier with $5.6 million. Marvel’s latest blockbuster sequel has obviously slowed down over the past few weeks, but its tally is still one of the highest for the studio. So far, the film has made $244 million domestic and $695 million worldwide.

Rio 2 comes in at number 6 with $5.1 million, which brings its domestic total up to $113 million. Fox’s animated sequel continues to trail its predecessor by a greater and greater margin, leading us to believe this is the last we’ll see of the colorful birds of the Amazon.

In at number 7 is Mom’s Night Out with $4.2 million. We didn’t expect much from this family-friendly comedy given its lack of marketing, but the film was able to drum up a decent tally thanks to the Mother’s Day weekend.

The number 8 film is Legends of Oz: Dorothy’s Return (read our review) with $3.7 million. A familiar property and family-friendly appeal couldn’t help this one, which will seemingly disappear almost as soon as it appeared.

Divergent is the number 9 film this weekend with $1.7 million. Lionsgate and Summit’s YA adaptation, the heir to the throne of Hunger Games and Twilight, has done very well for itself with $145 million over 8 weeks.

Rounding out the top 10 is Brick Mansions with $1.4 million. Unfortunately, the last completed film starring Paul Walker couldn’t get many audiences in the theaters. The film likely bows out of the top 10 with $18 million over 3 weeks.

Outside the top 10: Jon Favreau’s new movie Chef made $204,000 on six screens for an average of $34,000 per screen. The film expands to more markets next weekend.
