Box office: 'Furious 7' still running strong

"Furious 7" enjoyed a victory lap over the weekend, becoming only the third film ever to make $1 billion internationally and leading the domestic box office for the fourth straight week. But the movie that's poised to topple the Universal juggernaut, Marvel's "The Avengers: Age of Ultron," revved up overseas with a massive $201.2 million debut.

In North American theaters, "Furious 7" had enough left in the tank to top all films with an estimated $18.3 million, according to studio estimates Sunday.

This weekend, the only new wide release was the Blake Lively fantasy romance "The Age of Adaline." The Sony comedy "Paul Blart: Mall Cop 2" held up stronger than expected to take second place.

But the reign of "Furious 7" is effectively over now that the highly anticipated "Avengers" sequel is on the way. Though it doesn't open in North America until Thursday, it debuted in 44 countries and territories this weekend.

Estimated weekend ticket sales:

1. "Furious 7," $18.3 million.

2. "Paul Blart: Mall Cop 2," $15.5 million.

4. "Home," $8.3 million.

5. "Unfriended," $6.2 million.

6. "Ex Machina," $5.4 million.

7. "The Longest Ride," $4.4 million.

8. "Get Hard," $3.9 million.

10. "Woman in Gold," $3.5 million.
