“The Angry Birds Movie,” adapted from the popular mobile game, earned an estimated $39 million in North America during its opening weekend, taking the top spot at the box office. Rovio Entertainment, the company behind the game, self-financed the $73 million film, while Sony Pictures Entertainment handled distribution and marketing. “Rather than go the traditional route and license its characters to a studio to develop,” reports The Wall Street Journal, “Rovio backed the movie in an attempt to turn a game played on small screens into a full-fledged Hollywood franchise.” Other top earners included “Captain America: Civil War” (which became this year’s first film to earn $1 billion worldwide), “Neighbors 2: Sorority Rising” and “The Nice Guys.”
