Associated Press: The “Age of Ultron” is not over. The Avengers sequel topped the domestic box office for the second weekend in a row with an estimated $77.2 million, according to estimates. The film has earned a staggering $312.9 million in just 10 days in theaters, tying with “The Dark Knight” to become the second-fastest film to do so. “Hot Pursuit,” meanwhile, failed to make a significant mark in its debut weekend, earning a less-than-impressive $13.3 million. “Critics were very tough on” the Reese Witherspoon and Sofia Vergara buddy comedy.
