20th Century Fox’s movie adaptation of Marvel Comics’ foulmouthed anti-hero Deadpool is proving to be a box-office monster. It had the highest-grossing opening weekend of any Rated-R film in history and has already surged past the $500 million mark. A tidy sum, especially when you consider its relatively meager budget of $58 million (compare that to the $220 million it cost to make The Avengers: Age of Ultron).
