Perfect studio pitch.

“The Avengers” sequel fell 50 percent in its third weekend  to $38.8 million (about right), “Mad Max: Fury Road” debuted at $44.4 million domestically (a bit low considering the great reviews), but the big story this weekend is “Pitch Perfect 2” and its $70 million debut.

What the hell?

The first “Pitch Perfect,” which was released three years ago September, debuted at $5 million in 335 theaters and grossed a total of $65 million. This one has already slammed past that. $70 million? That's “Star Trek” territory. What are these things about again? Girls singing and quipping and being empowered? Or something? Well, Universal knew what it was doing with this one. It got decent enough reviews, 69% on Rotten Tomatoes, but that’s not close to “Mad Max”’s 98%. Yet look who killed at the b.o. Maybe “Max”’s good reviews scared off the action-adventure crowd.

I found this interesting: “PP2” is the directorial debut of Elizabeth Banks, whom I just saw in the Brian Wilson biopic “Love & Mercy” (recommended), and who always kills as Effie Trinket in the “Hunger Games” movies. Good for her and for female directors in general. Get those stories out there. Even if I have zero interest in seeing them.
