The ladies of "Pitch Perfect 2" hit all the right notes opening weekend, amassing a $70.3 million debut, according to Rentrak estimates Sunday.

The Elizabeth Banks-directed sequel to the 2012 sleeper hit and video on demand phenomenon cost Universal Pictures only $29 million to produce and was expected to open in the $50 million range. The first film, for comparison, grossed only $65 million domestically across its entire run.

Audiences for the musical comedy were 75 percent female and 62 percent under the age of 25, according to Universal.

George Miller's critically acclaimed "Mad Max: Fury Road," landed a distant second in its debut weekend with a solid and expected $44.4 million from 3,702 locations. The high-octane, post-apocalyptic film cost a reported $150 million to make and stars Charlize Theron and Tom Hardy.

Although it cost significantly more than "Pitch Perfect 2" to produce and didn't come close to matching its opening, "Mad Max: Fury Road" still had a promising first weekend in theaters.

1. "Pitch Perfect 2," $70.3 million.

2. "Mad Max: Fury Road," $44.4 million.

3. "Avengers: Age of Ultron," $38.8 million.

4. "Hot Pursuit," $5.8 million.

5. "Furious 7," $3.6 million.

6. "Paul Blart: Mall Cop 2," $3.6 million.

7. "The Age of Adaline," $3.2 million.

8. "Home," $2.7 million.

10. "Far from the Madding Crowd," $1.3 million.
