LOS ANGELES — In a summertime battle of sequels, a pair of kooky cops beat out flying dragons for the top box office spot.

The R-rated comedy “22 Jump Street” debuted in first place at $60 million followed by “How to Train Your Dragon 2” at $50 million. It’s rare for two films to open with such big numbers on the same weekend, said Paul Dergarabedian, of box-office tracker Rentrak. The original versions of “Dragon” and “Jump Street” were springtime releases, and their strong performances led studios to offer sequels in summer.

Estimated weekend sales were:

1. “22 Jump Street,” $60 million

2. “How to Train Your Dragon 2,” $50 million

3. “Maleficent,” $19 million

4. “Edge of Tomorrow,” $16.2 million

5. “The Fault in Our Stars,” $15.7 million

6. “X-Men: Days of Future Past,” $9.5 million

7. “Godzilla,” $3.2 million

8. “A Million Ways to Die in the West,” $3.1 million

9. “Neighbors,” $2.5 million

10. “Chef,” $2.3 million
