A few dozen superheroes lifted "Avengers: Infinity War" to a record $250 million in ticket sales over the weekend, narrowly surpassing "Star Wars: The Force Awakens" for the highest opening weekend of all-time. "Infinity War" also set a new global opening record with $630 million, even though it's yet to open in China, the world's second-largest movie market. It opens there May 11. "The Fate of the Furious" previously held the worldwide mark with $541.9 million.
